 slashdot effect With that said, this will not prevent an overload of the server since the Slashdot effect. I guess this will only work for revisiting users. Result is the perfect storm completely overloading the web server. While throughout the peak the response time went ‘sky high’, as already seen in the graph above. Therefore the impact of the Slashdot effect is clearly visible in the response time of the web server. That said, this happened at exactly 12 dot 00PM. Now look, an explanation may be that at identical time, the Europeans take a lunch break and the east coast of the USA awakens. Now let me tell you something. We use the WP Super Cache plugin. We use WordPress as blogging software. Therefore, theoretically this cache module most possibly should handle this smoothly. We never had tested it under Slashdot effect conditions, where thousands of users simultaneous seek for to access identical webpage on the website. You should take this seriously. I had already done tests with it and it seems to improve performance significantly when reloading identical page multiple times.

 slashdot effect Amidst the first thing you read about improving the performance of WordPress is to use caching.

Whenever causing the site to buckle under the strain, when all those Slashdot readers start crashing the party, it can saturate a smaller website completely.

Now this can easily throw thousands of hits at the site in minutes. Often plenty of readers will hit the link to read the story, when Slashdot links a site. Now look, the site is said to be Slashdotted, when this happens. I’m sure that the Slashdot website serves around 3 million pages on weekdays, and slightly less on weekends.

 slashdot effect Basically the OliNo website is hosted in the Amazon Elastic Computer Cloud.

In our case we do not use the access log.

Another option we can use it so disable access logging. Error logging will still be enabled. Writing log information is a time consuming process. You see, this can take up valuable time it’s just a case of writing the information,, Apache keeps the log files open. Although, we can save few processor cycles by disabling it. We simply comment out the log lines in the configuration file, to do this. At 08 dot 35AM the server load was already increased to 27, a clear indication that the server is already overloaded. While using the Linux p command, is mostly about 3 during normal traffic, as long as the first group of visitors came to the website.

Normally this still young Renewable Energy website gets around 100 visitors per day.

Now this effect was clearly visible on the worldmap of google analytics. Within one hour, now this number climbed to more than 1000 visitors. Notice, at the moment of the post, Europe was just waking up, the US westcoast was just preparing to bed and the US east coast was still sleeping. Therefore this gives a clear indication that the web site needs plenty of tweaking to get a better performance. However, amongst the first things we did is to analyse the website with the very nice Firefox plugin YSlow. I know it’s also suggested to use minified version for the Javascript files. Remember, preferably you have to have only one Javascript and one CSS file. Seriously. Tip given there’s to combine as much Javascript files and Stylesheets into both single files.

Improvements suggestions are sorted on most impact on top.

The webpage has 14 external Javascript files, 6 external CSS StyleSheets and 24 CSS background images.

I am sure that the tip to minimize HTTP requests, is the first we must tackle. In the course of the day more visitors came from different parts of the world. So, in the evening we have received 27169 visitors from 134 countries/territories. This is the case.a lot of visitors came still from the USA. You can find more info about this stuff here. 1024 MB reserved for Apache / 20MB per Apache thread ~ 50 MaxClients.

Setting this value isn’t isn’t shown.
Then the tip of Apache is to divide the available quantity of memory for Apache by the quantity of memory used in Top by a single Apache thread. It seems we need to reduce the amount of MaxClients from 150 to 50 for our Apache configuration. Fact, our Apache thread uses between the ‘1620MB’ per thread. Among the first tips is to check the MaxClients option. Our Apache webserver isn’t tuned for performance. Basically, so it is a first step we can take. Remember, the current setting is Setting this value must result in error in the log. On p of this, look, there’s a great document about Apache Performance Tuning on the website of Apache. Yes, that’s right! We are clearly guessing now, as you can see.

One way to find the real bottleneck your personal performance tests on an identical non production set up.

The bottleneck can be CPU, IO or network.

Repeat this process until you are satisfied with the performance.

Lots of us know that there are a few options which can be tuned like the Apache webserver, the MySQL database or even the Linux kernel. During these tests the load on the server can be controlled and the server can be monitored closely. However, perform your load test, find the bottlenecks, try to solve them by adjusting the set up, do your performance tests again. With that said, this process is iterative. Anyways, the response time of the website is monitored by a global monitoring network service of Pingdom.

They have probe servers which are located in the USA, Canada, UK, Sweden and France.

With an interval of 5 minutes the response time of the website is measured from the different locations.

Notification is send when the server is unavailable. Looking at the details reveals that user processes is only taking 30percent CPU usage and the processor is still 16 dot 4 idle. You can find a lot more information about it here. The server load snapshot taken at 08 dot 35AM is a clear indicator the server is overloaded. CSS file and theme images are loaded on the CDN this will offload a bunch of HTTP request from the main web server, when the javascript file. You can find some more information about it here. Content is delivered with top-notch possible performance, requests for your objects are automatically routed to the nearest edge location.

Amazon CloudFront delivers your content using a global network of edge locations.

It should also result in a faster loading website for the visitor as the content to load is located more closely to the physical location of the visitor.

Now look, the second tip to use a Content Distribution Network is something Amazon can offer with CloudFront. Some digging on the internet shows that using Amazon Cloudfront will double the bandwidth costs for your website. Therefore this generates 914 KB x 2320 = 2 GB per hour of data traffic. Consequently, in the course of the peak we got 2320 visitors per hour. Now pay attention please. So this calculates back to 590 KB/s of continuous traffic. So this should not be the bottleneck. With 914 KB, the webpage is quite large. That said, this makes sense, as with Amazon EC2, you only pay for running instances per hour. However, gether with the announcement of Amazon for their loadbalancer solution they announced a feature called autoscaling. I’m sure that the loadbalancer will balance the load over the running web server instances. Autoscaling could ‘startup’ more instances to handle the increased load, when there’s a huge peak in visitors.

With that said, this could be very effective for surviving the slashdot effect.

Auto scaling will stop a lot of the running instances, when the load drops again as the visitors are gone.

Now this makes it possible to start / stop instances on the basis of the load of a number of instances using a voting mechanism. I thought I should leave my first comment. I don’t know what to say except that I have enjoyed reading. Sounds familiar? I recently came across your blog and been reading along. I’m sure you heard about this. Nice blog. Essentially, I will visit this blog very often.

So it is a cool article and I have posted a link to my twitter account.

I will also refer my customers to your AWS experience.

Surely it’s a freeware. Actually, you can check my very own ol CloudBerry Explorer that helps to manage S3 and CloudFront. A well-known fact that is. Our organisation will contribute to reach this goal. We found an appropriate name for our organisation, OliNo, that is a word joke for No Oil! It’s a combination of two Catalan words.Oli and No. Gether they mean Oil No! Let start a civilization which provides for its energy using renewable energy. Therefore, this effectively means we need at least 4 small EC2 instances.

Until the time comes when Amazon will offer a load balancing service in their EC2 environment, people are forced to use a software based load balancing solution.

Effectively quadrupling the current cost price of using a single EC2 instance.

Actually the next step will be running two small instances with the apache webserver with wordpress and a third instance with MySQL. To be able to handle a bigger load on the webserver one could start using multiple instances. I am sure that the web traffic gonna be load balanced over the two web servers. That said, this instance has 7 memory GB, 1 EC2 Compute Unit, 160 GB of instance storage, ’32bit’ platform. Fact, the OliNo website is using a small instance type.

One EC2 Compute Unit provides the equivalent CPU capacity of a ‘0 2’ GHz 2007 Opteron or 2007 Xeon processor. Instance is running in the ‘useast1b’ datacenter of Amazon. With that said, this translates back to around 39 visitors each minute. Eventually, the overall amount of visitors kept growing any hour. See also the results of a recent performance analysis and the current MySQL settings. Now pay attention please. The amount of visitors per hour went slowly down with a few hundred visitors less any hour until it stabilised at 11 dot 00PM / 05 dot 00PM, right after the peak. At 12 dot 00PM / 06 dot 00AM. At the peak 03 dot 25PM / 09 dot 25AM, the OliNo site received 2320 visitors per hour. Is it faster to keep them on the they are already in the browsers cache of the visitor, Google servers?

It Gives You Much Needed Breathing Room To Plan Ahead Must The Spike Continue For Weeks – Unixy

 slashdot effectAnother question isSo the question is this. Is it allowed and does it work?

We use Google Javascripts for showing Ads with Google Adsense and monitoring traffic using Google Analytics.

Does it make sense, to take these scripts and combine them with your Javascripts to improve performance? Notice, what about Javascript from Google? In the case of a WordPress blog, say for instance blog.unixy.net/2010/03/bargain bin fully managed dedicated servers/,upon visiting the Bargain Bin blog link, the server where blog.unixy.net is hosted will need to perform a couple of tasks to render the page and send it the HTML results back.

 slashdot effect Under extended peak traffic periods, these tasks when repeated continuously overwhelm the server and cause it to slow down and sometimes to crash.

Whenever querying the database, and retrieving files from disk amongst other tasks, the tasks consist of running PHP scripts. It gives you much needed breathing room to plan ahead must the spike continue for weeks. In most cases, servers collapse as long as the serverside processing that needs to occur to produce the HTML that sent to the browser. Here on this blog, we are intending to cover one trick that is used in Web social circles to weather shortlived traffic storms. So this trick is effective and does the job Whether Perl with a database backend,, or the serverside script is written in PHP, Ruby. You also agree that your personal information might be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy. By submitting my Email address I confirm that I have read and accepted the Terms of Use and Declaration of Consent.

 slashdot effect While bypassing all of that heavy processing, So if all the server does is produce the HTML code and send it back to the browser, we the above-mentioned rules before the WordPress rules.
Now that we obtained the HTML, we are planning to add a.htaccess rule to temporarily redirect all requests to the article /2010/03/bargainbinfullymanageddedicatedserversbargainbin.html. Basically the GET command comes as part of the libwwwperl package, that is available for both Linux and Windows. So 302 rule means that it’s a temporary redirect.

That’s so it’s website optimization friendly and does not break your links as SE see them.

I hope you enjoyed this short article.

Consider that must you be one of our customers, we could be very happy to complete this workaround on your server for no extra charge. Those instructions can work for about any CMS or portal. Increasingly about any ‘technologyrelated’ subject, the effect gets its name from the Slashdot Web site, a discussion forum originally about Linux and related software. Did you know that the effect is obviously far more noticeable on smaller sites and the surge in traffic sometimes will slow a site down or make it impossible to reach. Now look, the Slashdot Effect is the sudden, relatively temporary surge in traffic to a Web site that occurs when a ‘hightraffic’ Web site and similar source posts a story that refers visitors to another Web site. However, the Slashdot Effect can be perceived when any large Web site posts a ‘high interest’, widely publicized story about another site.

I Mean It Could All Even Happen At The Isp Provided Their Pipe To The Net Was Big Enough

 slashdot effect I’m almost sure I would like to thank you for posting to Geek.com in response to our questions.

We don’t often get direct answers, usually just banal quips from clueless hacker dudes.

So in case you will, any and all information from the horses mouth, is always greatly appreciated. Any site that’s offering up something new or that gets Slashdotted I’d say if they didn’t have the bandwidth to keep it completely inhouse. You also agree that your personal information Therefore if you want serious content delivery and to avoid the Slashdot effect, don’t get me wrong P2P still has a niche to fill and for pirating it is the best solution but, P2P is not the way to go. Considering the above said.a BitTorrent download only consumes bandwidth in either direction when it’s started, and immediately stops uploading as soon as it’s done downloading. It also tends to saturate downlink, which is what you want, it does tend to saturate uplink when transferring.

Have you heard of something like this before? BitTorrent peers don’t act as alwaysup servers like Napster ones do. Basically, the Slashdot Effect is the sudden, relatively temporary surge in traffic to a Web site that occurs when a hightraffic Web site or other source posts a story that refers visitors to another Web site.

We Actually Should Forget About The Security Aspects For A Second As If That Weren’t Hard Enough

 slashdot effect Those at Midhurst and Shoreham are no longer in use by the Diocese. BitTorrent peers don’t act as ‘always up’ servers like Napster ones do.

a BitTorrent download only consumes bandwidth in either direction when it’s started, and immediately stops uploading whenever it’s done downloading.

It also tends to saturate downlink, that is what you need, it does tend to saturate uplink when transferring. Call me selfish but, the last thing I need is 10000 people striving to connect to and download files from my rig.

Know what, I personally don’t seek for all of my precious bandwidth consumed and my workstation crushed under the load being that some hottie just released a brand new song or being that CNN has the latest on a new terrorist attack.

 slashdot effect We actually need to forget about the security aspects for a second, as if that weren’t hard enough.

I should like to thank you for posting to Geek.com in response to our questions.

We don’t often get direct answers, usually just banal quips from clueless hacker dudes. Therefore if you will, any and all information from the horses mouth, is always greatly appreciated. Thus, a service that provides individualized content that gets Slashdotted should not necessarily benefit from the distributed load concept. Analysts point out that the Swarmcast and BitTorrent solutions only work when the huge number of surfers is requesting quite similar content. Of course since it can run as multiple virtual Web servers, a IDC analyst pointed to IBM’s ‘Linux powered’ ‘ZSeries’ servers as a good idea in those cases, In those situations, more powerful hardware may again become only one solution.

 slashdot effect Swarmcast was developed by OpenCola, a Canadian software company.

It shifts into P2Pish sharing only when the server’s load gets high, bitTorrent is Bram Cohen’s software approach to similar solution.

While easing the server’s burden, whenever users install the Swarmcast client software on their PCs, the Swarmcast server side software breaks requested content into pieces which are shared user to user by the client software. Actually the approach is extremely interesting since the more people striving to get at particular content, the easier that sharing becomes as long as the larger number of users. Idea of a server pool has better merits. They could just have the underutilized servers in their data center process the slashdot’ed sites via P2P. I mean, it could all even happen at the ISP provided their pipe to the net was big enough.. People pulling it from you get alternative story than they should had they been able to access the actual site, TQBrady writes How long before hackers write a script that changes your local copy of the content?

Secure hashing information about the file to be downloaded is returned as part of the http request which kicks it off, and data which doesn’t match that hashing information is later rejected, peers can’t fool you into downloading alternative file than you meant to, with BitTorrent.

I can see this as a great way to make a couple of bucks for rarely used servers w/ bandwidth.

Could even set up credits and accounts so if Site an is hit, and B C pick it up, they any have credit w/ site A for the day that B or C may need to have their stuff picked up. Charge a little for all the usage. I know that the Switch’s Paltry Launch Lineup Doesn’t Justify a DayOne. In my opinion the P2Ptype solution makes tal sense, and is a great example of thinking outside the write, as for the software.

Any site that’s offering up something new or that gets Slashdotted if you look for serious content delivery and to avoid the Slashdot effect, better solution but, P2P any BitTorrent peer only uses about as much upload as it does download. Every one only has to be at about ‘break even’ for the system as a whole to work, the upload burden is distributed across all downloaders.

It Could’ve Been Like Muhammed Ali’s Comeback Ur – Slashdot Meets The Crossroads Years Later

 slashdot effect It shouldn’t be very similar company or schools/gov’ts as you pointed out, So if they didn’t have the bandwidth to keep it completely inhouse. Within two its inception years, the sheer weight of Slashdot’s userbase had overwhelmed Malda, Bates, and the small team that had coalesced to keep the website running.

The deal allowed the Slashdot team to expand and begin lifting the burden off of Malda and Bates to a more manageable load.

In late June of 1999, Maldaannouncedwhat my be the company’s first of three acquisitions. While using meager ad revenue to support a dogged endeavor as programmer and de facto choke point of the thousands of comments streaming through Slashdot’s servers, malda had already shifted his busy focus to Slashdot. Linux website Andover.net for $ 5 million in cash and $ 7 million in Andover stock at IPO price. In hindsight, meta moderation serves as a sort of protoupvote that can curb the noise of the standard trolling and off pic blabbering that plagues all online discussion. Basically to submit tips, begin discussions, and police others into contributing meaningfully to the news at hand, slashdot quickly carved out a ‘much beloved’ and loyal following of finicky tech geniuses and IT nerds eager to not only give feedback to Slashdot.

 slashdot effect Slashdot system, described by Malda as meta moderation, empowered users to boost good comments from others and knock poor ones.

Malda looks upon the time as the support structure that kept Slashdot afloat in the turbulent dotcom era, while critics at the time were wary of the viability of a fully consolidated Linux portal system and members of the Slashdot community expressed concern for an even larger risk of an audience full of newbies and trolls.

Accordingly the time under as the company merged with Fairfax County.net proper was shortlived Va.-based VA Linux Systems Linux portal, benefactor of thebiggest IPOduring the dotcom boom and creator of open source code database SourceForge in 2000 in a $ 4 billion deal. Fact, at the headquarters of long running IT and Geek news social media platform Slashdot, everyone involved is mounting an all out push to break through the relative obscurity the name has faded into within recent years and jockey to the forefront of the collective Internet consciousness. It should be like Muhammed Ali’s comeback tour. Known the chips are down, and on its 15th birthday, Slashdot is earnestly attempting to get back in the game. Furthermore, it could just as easily fade into the Wayback Machine. I’m sure that the alchemy of a comeback is a problem to define, and even harder to perform.

 slashdot effect Its biggest push is to confidently establish itself in a completely new arena.

The company used HTML5 to develop a mobile version that worked seamlessly across all smartphone devices something that the diverse Slashdot community could appreciate.

With the guidance of a certain amount Slashdot’s most prominent power users, in response, the team worked to develop a mobile platform. Wellman said that amidst the biggest pain points for the Slashdot user experience laid in the rendering of the website in a smartphone browser, while receiving feedback from the community. Considering the above said. Actually the layout, in combination with the new logo, is a sort of grand update that will continue with a future tablet app and perhaps even a ‘full blown’ redesign to better suit the company’s more diverse goals.

 slashdot effect Wellman indicated that a mobile version is just the first of many steps in creating a tally new and modernized Slashdot.

Slashdot’s influence had already expanded well beyond the reaches that Malda, Bates and crew could’ve foreseen, and it was only getting bigger.

At that point, the extent of power and influence that Slashdot held was one rarely seen in Internet history it even became a verb. Basically, slashdotting was the colloquialism for The Slashdot effect, a noticeable phenomenon that involved a website’s servers becoming overloaded for a reason of being on the other end of a link on an interesting Slashdot article. Now let me tell you something. It’s also something of a Internet folk tale that Malda, in Slashdot’sfirst editorial, was a driving force in convincing Netscape to release its browser for free to the public.

If only to its own community,. Malda sees the challenge ahead and hopes that his little website that could can beat those odds and make itself a star again. In perspective, he’s also proud of what it’s accomplished. On September 18, 2012, Geeknet announced that it had sold Slashdot, with Freecode and SourceForge, to Dice Holdings for $ 20 million in cash. It didn’t come as much of a surprise, to followers of Slashdot. That’s right! Geeknet’s intentions began swirling as early as May. You should take it into account. On paper, the editors felt strong about the decision. Geeknet Chairman Ken Langone indicated that Geeknet wanted to focus full scale on ThinkGeek a reliable source of profit for the company, when asked for the reason. I’m sure you heard about this. While considering that ThinkGeek a company with roots in the late ’90s broke through when it wasSlashdottedin September of Slashdot, with the last vestiges of Geeknet’s non retail properties, is now managing a transition above all, the news is poetic in a way.

What really is known is what continued in trade headlines.

Whenever becoming VA Software, vA Linux Systems ok a major hit in the dotcom burst and was forced to truncate its hardware division in 2001.

In 2004, the company sold its Animation Factory Software to Jupitermedia Group, and its enterprise business to ‘cloud software’ company CollabNet just two short years later.

Continued to struggle making revenue, the company rebranded to SourceForge after its sales. However, a separate company, Geeknet, was established and the remaining assets Slashdot, SourceForge and Freecode were subsequently merged. Besides, the company is holding interviews with some popular Slashdot users, including celebrities and tech luminaries.

As Slashdot enters the month of its 15th birthday, the team was working on more surprises to excite its community and hopefully attract new users.

While considering the website has only been redesigned three times in its existence, While it’s available via retail channels, users canearnone via a flawless submission into the website’s logo redesign contest, a monumental occasion.

For its community, the website is helping to coordinate global gatherings of users via Meetup and offering special merchandise in the sort of a 15th anniversary tshirt. Drobick still was hesitant to separate the identity of Slashdot with the entirety of the Geeknet umbrella, when speaking on the acquisition a few days just after the ink dried on the agreement. His eye wards the future of the company still had a longgame attitude that Slashdot is bound to make the comeback as long as the company put in the work to make it happen., while the longstanding community held fast, traction was harder to come by.

During this tumultuous period, Slashdot was also experiencing its first slump.

Malda said that though he continued to contribute in the tradition of Slashdot’s voice, it often became difficult.

Tides turned in the late 2000′ As the traditional geek community became outmoded by other, more Web ‘0 focused’ social platforms just like Myspace, Digg and Twitter, less users were joining the system, while it managed to remain a steadily popular source throughout its parent company’s identity crises. Of course in June,SlashDataCenterlaunched as an arena specifically catered to IT specialists. Fact, cameSlashBI, a site that specifically curates stories dealing with the business intelligence sector. Wellman began this updating process with the introduction ofSlashdotTVin March of 2012, a multimedia hub that infused the website with videos focusing on interviews with wellknown tech figures as well as explainer pieces on larger IT concepts. Consequently, a mere nine days later,SlashClouddebuted with articles relating to cloud computing software and implementation. Now pay attention please. From there, Wellman and his team implemented channels, a delineation of content previously missing from the Slashdot ethos. On p of that, just three short months later, it was 120000, In February of 1998, Slashdot was receiving an average of 20000 pageviews per day.

Whenever coding sorcery, Linux tweaking and tech discussions from their Michigan home base, while a number of Americans were still connecting to the Internet through AOL, malda and Bates became ubermoderators in the finer points of hacker news. While attracting users far and wide and multiplying rapidly, with that said, this technique cut through the general noise and conversational buildup of the Listserv model. Durney said that the intentions are relativelyvery simple. Its community, dice Holdings was interested in Slashdot and its ilk not only for its long running reputation on the Internet. No employee has publicly left being that the acquisition there’s still a question of motive, while things look relatively set in place on Slashdot’s end as of this writing. Then, Dice Holdings is entering new ground with its first foray into a publishing platform, as a predominantly jobsboard focused holding group. More than satisfying the needs of the community, the mobile application is meant to serve as a gateway for casual readers to get a better insight into the Slashdot community. Whenever hoping that the new redesign will lure new eyes onto pages, the company is hedging its bets on the viability of mobile.

By the way, the final quarter of this year could be it, So in case ever there was a performance moment for Slashdot.

Now in the full process of a transition over to Dice Holdings, it’s unclear how things will truly look once the dust settles.

On a call with Michael Durney, SVP, finance and CFO of Dice Holdings, said that the company’s intent was to keep Slashdot asis. It’s almost impossible to trust for sure. That’s right! While restoring it, giving it the tender consideration its gone without in the course of the website’s rough period and implementing its strategy to form new communities can feel like its backed by winning enthusiasm, the positive discussion around the community particularly in reviving it.

So It Is Ridiculous: Leadership Motorsports Life

 slashdot effect Now look, the level of unknown obstacles that will be ahead of Slashdot, already scrambling to make a play that could put it back in the game, could just as easily ss it back into jeopardy.

Between the words left unsaid by Malda and current Slashdot Editor in Chief Stephen Wellman, it’s clear that all parties treat the time as a still healing wound that’s better left untouched.

Accordingly the time between Slashdot’s heyday in the early 2000’s and the events of last year are somewhat of a mixed history in Slashdot’s existence. So Slashdot Effect is the sudden, relatively temporary surge in traffic to a Web site that occurs when a high traffic Web site and akin source posts a story that refers visitors to another Web site.

 slashdot effect Therefore the Slashdot Effect can be perceived when any large Web site posts a ‘highinterest’, widely publicized story about another site.

The effect is obviously a lot more noticeable on smaller sites and the surge in traffic sometimes will slow a site down or make it impossible to reach.

Increasingly about any ‘technology related’ subject, the effect gets its name from the Slashdot Web site, a discussion forum originally about Linux and related software. You also agree that your personal information might be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy. Seriously.

Did you know that the article also suggests that look alike sites are lessening the Slashdot Effect. That said, this means that sites like geek.com and gizmodo.com are diluting the Slashdot Effect. So it’s ridiculous. Now look, the article asserts that the tal amount of news sites Slashdot is linking to has skyrocketed. Nevertheless, that has reduced the impact Slashdot can make on every individual site’s traffic. Keep reading.a recent survey performed by OSTG, released on March 22nd shows that 73percentage of slashdot readers will increase their use of RSS feeds in the next year.

 slashdot effect More than a quarter of respondents are reading more than five sites via RSS feeds.

Virtually, a decline in the Slashdot Effect aside from anecdotal evidence, there were no plausible reasons explored in the article, So if there is.

Perhaps, way more visitors to Slashdot have already linked to the source from their RSS news and blogs reader. Perhaps, the visitors to Slashdot are becoming increasingly focused on the community comments themselves rather than the news links. Perhaps, Slashdot has grown beyond its original tech editorial focus and is linking more frequently to sites beyond the conventional high tech list. Perhaps, the proliferation of links to CNET and identical tech sites have, over time, caused readers to visit those sites as part of their normal daily reading habits.

Business Week Online’s article Less Impact from the Slashdot Effect leaps to conclusions about why the Slashdot Effect has weakened over the last 12 months. To be honest I do take issue with what appears to be lazy journalism in citing causes for the decline, while I do not necessarily question an overall decline in the percentage of traffic that other tech news sites attribute to Slashdot. At a minimum, Actually I would hope that an interested journalist or anthropologist will take a closer look at Slashdot to understand if most of us know that there is a correlation between its increasing page views and visitors and declining traffic referrals. Rather than simple advertising mentality trend lines, my sense is that we might be seeing the evolution of this worldwide community and its dynamics. Whenever in accordance with Jupiter research, in a report published on March 12th and entitled RSS readers, Really Simple Syndication received little consumer attention prior to 2003, despite its availability since the late 1990s.

At Moment Of Post Europe Was Just Waking Up Us West-Coast Was Just Preparing To Bed (10: Olino

 slashdot effect 12 online percent consumers use RSS feeds in the apartments and in tooffice. By submitting my Email address I confirm that I have read and accepted Terms of Use and Declaration of Consent. I won’t be able to see logic here. For instance, sheer growth of Slashdot unique visitors and page views negates this theory.

Article also suggests that growing number of tech news sites is another reason that Slashdot Effect is diminishing. Value isn’t ain’t shown.

Tip of Apache is to divide available quantity of memory for Apache by quantity of memory used in Top by a single Apache thread.

Our Apache thread uses between to’1620MB’ per thread. 1024 MB reserved for Apache / 20MB per Apache thread ~ 50 MaxClients. Remember, it seems we need to reduce the amount of MaxClients from 150 to 50 for our Apache configuration. Setting this value in the course of the peak response time went sky high, as already seen in graph above.

Result is perfect storm completely overloading web server.

Now, an explanation gonna be that at identical time, Europeans take a lunch break and east coast of USA awakens. Impact of Slashdot effect is clearly visible in response time of web server. Then again, look, there’s an ideal document about Apache Performance Tuning on website of Apache. Generally, amongst to first tips is to check MaxClients option. Our Apache webserver isn’t tuned for performance. I am sure that the current setting is Setting this value must result in error in tolog. So, that’s a first step we can take. With all that said… Therefore the Slashdot Effect can be perceived when any large Web site posts a high interest, widely publicized story about another site. Then the effect is obviously a lot more noticeable on smaller sites and surge in traffic sometimes will slow a site down or make it impossible to reach. Therefore, increasingly about any technologyrelated subject, effect gets its name from Slashdot Web site, a discussion forum originally about Linux and related software.

 slashdot effect Accordingly the Slashdot Effect is tosudden, relatively temporary surge in traffic to a Web site that occurs when a high traffic Web site and akin source posts a story that refers visitors to another Web site.

Response time of website is monitored by a global monitoring network service of Pingdom.

Notification is send when server is unavailable. With an interval of 5 minutes response time of website is measured from different locations. That’s interesting. They have probe servers which are located in toUSA, Canada, UK, Sweden and France. Therefore this should not be tobottleneck. In the course of the peak we got 2320 visitors per hour. Then, this calculates back to 590 KB/s of continuous traffic. With 914 KB, webpage is quite large. So this generates 914 KB x 2320 = 2 GB per hour of data traffic. Looking at details reveals that user processes is only taking 30percent CPU usage and processor is still 16 dot 4 idle. Server load snapshot taken at 08 dot 35AM is a clear indicator server is overloaded. ‘auto scaling’ will stop most of to running instances, when load drops again as visitors are gone.

 slashdot effect So this makes sense, as with Amazon EC2, you only pay for running instances per hour.

This makes it possible to start / stop instances on the basis of load of a number of instances using a voting mechanism.

With that said, this could be very effective for surviving slashdot effect. So loadbalancer will balance load over running web server instances. There’s a lot more information about it here. ‘auto scaling’ could start up more instances to handle increased load, when there’s a huge peak in visitors. Gether with announcement of Amazon for their loadbalancer solution they announced a feature called auto scaling. At 08 dot 35AM server load was already increased to 27, a clear indication that server is already overloaded.

 slashdot effect Whenever using Linux p command, is all about 3 during normal traffic, whenever first group of visitors came to towebsite. With that said, this instance has 7 memory GB, 1 EC2 Compute Unit, 160 GB of instance storage, ’32 bit’ platform. One EC2 Compute Unit provides equivalent CPU capacity of a 02 GHz 2007 Opteron or 2007 Xeon processor. Instance is running in us east 1b datacenter of Amazon. Did you know that the OliNo website is using a small instance type. So that’s a cool article and I have posted a link to my twitter account. You can take a glance at my very own ol CloudBerry Explorer that helps to manage S3 and CloudFront.

I will also refer my customers to your AWS experience. Undoubtedly it’s a freeware. Let start a civilization which provides for its energy using renewable energy. And so it’s a combination of two Catalan words.Oli and No. Our organisation will contribute to reach this goal. We found an appropriate name for our organisation, OliNo, that is a word joke for No Oil! Gether they mean Oil No! Theoretically this cache module most possibly will handle this smoothly. Just think for a moment. I had already done tests with it and it seems to improve performance significantly when reloading really similar page multiple times. Considering above said. We never had tested it under Slashdot effect conditions, where thousands of users simultaneous need to access similar webpage on towebsite.

We use WordPress as blogging software.

We use WP Super Cache plugin.

Amidst to first thing you read about improving performance of WordPress is to use caching. Within one hour, therefore this number climbed to more than 1000 visitors. So this effect was clearly visible on worldmap of google analytics. This is tocase. At moment of topost, Europe was just waking up, US westcoast was just intending to bed and US east coast was still sleeping. Eventually, normally this still young Renewable Energy website gets around 100 visitors per day. I am wondering if it is worth effort with new WordPress 8 already announced where plenty of there problems will be solved automatically. Basically, with some having their own Javascript files, now this would mean we need to do loads of customizing, as we use a bunch of WordPress plugins.

Another question isSo question is this. What about Javascript from Google?

Is it allowed and does it work?

Does it make sense, to take these scripts and combine them with your personal Javascripts to improve performance? Is it faster to keep them on to they are already in browsers cache of visitor because Google servers? With that said, we use Google Javascripts for showing Ads with Google Adsense and monitoring traffic using Google Analytics. Then, OliNo website is hosted in Amazon Elastic Computer Cloud. You also agree that your personal information might be transferred and processed in United States, and that you have read and agree to Terms of Use and Privacy Policy.

Another option we can use it so disable access logging.

Intention to do this.

We can save few processor cycles by disabling it. Needless to say, this can take up valuable time it’s just a case of writing information because, even if Apache keeps log files open. In our case we do not use access log. Error logging will still be enabled. On p of this, writing log information is a time consuming process. Content is delivered with p possible performance, requests for your objects are automatically routed to nearest edge location.

Amazon CloudFront delivers your content using a global network of edge locations.

Some digging on internet shows that using Amazon Cloudfront will double bandwidth costs for your website.

It should also result in a faster loading website for visitor as content to load is located more closely to physical location of tovisitor. CSS file and theme images are loaded on CDN this will offload lots of HTTP request from main web server, when javascript file. A well-known fact that is. It’s an interesting fact that the second tip to use a Content Distribution Network is something Amazon can offer with CloudFront. Plenty of visitors came still from toUSA. In evening we have received 27169 visitors from 134 countries/territories. This is tocase. Throughout the day a lot more visitors came from different parts of toworld. By submitting my Email address I confirm that I have read and accepted Terms of Use and Declaration of Consent.

To be able to handle a bigger load on webserver one could start using multiple instances.

Until time comes when Amazon will offer a load balancing service in their EC2 environment, people are forced to use a softwarebased load balancing solution.

Effectively quadrupling current cost price of using a single EC2 instance. Certainly, web traffic may be load balanced over two web servers. Let me tell you something. Besides, the next step might be running two small instances with apache webserver with wordpress and a third instance with MySQL. Then, this effectively means we need at least 4 small EC2 instances. Yes, that’s right! I will visit this blog very often.

I thought I should leave my first comment.

I recently came across your blog and was reading along.

Nice blog. Notice, I don’t know what to say except that I have enjoyed reading. Among to first things we did is to analyse website with very nice Firefox plugin YSlow. With that said, this gives a clear indication that web site needs lots of tweaking to get a better performance. I’m sure that the improvements suggestions are sorted on most impact on top. And so it’s also suggested to use minified version for Javascript files. Preferably you have to have only one Javascript and one CSS file. Remember, webpage has 14 external Javascript files, 6 external CSS StyleSheets and 24 CSS background images.

I am sure that the tip given here goes to combine as much Javascript files and Stylesheets into both single files. Tip to minimize HTTP requests, is first we should tackle. That’s clearly a proven setup. All web server instances connect with a single MySQL database so mostly there’s a single state of towebsite. That’s where it starts getting really serious, right? This load balancing setup is similar how Slashdot has set up their hardware. That said, loadbalancer will balance load over running webserver instances. I guess this will only work for re visiting users. Therefore the remaining tips like adding Expires header and configure ETags are both cache related. Therefore this will not prevent an overload of server being that Slashdot effect. Considering above said. See also results of a recent performance analysis and current MySQL settings. The actual number of visitors per hour went slowly down with a few hundred visitors less any hour until it stabilised at 11 dot 00PM / 05 dot 00PM, after topeak.

I Don’t Know What To Say Except That I Have Enjoyed Reading – Olino

 slashdot effect At the peak 03 dot 25PM / 09 dot 25AM, the OliNo site received 2320 visitors per hour.

At 12 dot 00PM / 06 dot 00AM.

The overall number of visitors kept growing any hour. So this translates back to around 39 visitors any minute. You see, the bottleneck can be CPU, IO or network. Perform your load test, find the bottlenecks, try to solve them by adjusting the set up, do your performance tests again. With that said, most of us are aware that there are a few options which can be tuned like the Apache webserver, the MySQL database or even the Linux kernel.a single way to find the real bottleneck your performance tests on an identical ‘nonproduction’ set up. During these tests the load on the server can be controlled and the server can be monitored closely. For instance, we are clearly guessing now, as you can see. Repeat this process until you are satisfied with the performance. Of course, this process is iterative. To be able to handle a bigger load on the webserver one could start using multiple instances.

 slashdot effect Until the time comes when Amazon will offer a load balancing service in their EC2 environment, people are forced to use a softwarebased load balancing solution.

This effectively means we need at least 4 small EC2 instances.

Effectively quadrupling the current cost price of using a single EC2 instance. Remember, the web traffic gonna be load balanced over the two web servers. Then the next step could’ve been running two small instances with the apache webserver with wordpress and a third instance with MySQL. Then again, with some having their own Javascript files, now this would mean we need to do loads of customizing, as we use a bunch of WordPress plugins. I am wondering if that’s worth the effort with the new WordPress 8 already announced where plenty of there problems will be solved automatically. Now this calculates back to 590 KB/s of continuous traffic. With 914 KB, the webpage is quite large. Throughout the peak we got 2320 visitors per hour. So this generates 914 KB x 2320 = 2 GB per hour of data traffic. So this should not be the bottleneck. Nonetheless, often lots of readers will hit the link to read the story, when Slashdot links a site.

 slashdot effect Besides, the site is said to be Slashdotted, when this happens.

This can easily throw thousands of hits at the site in minutes.

Slashdot website serves around 3 million pages on weekdays, and slightly less on weekends. It’s a well while causing the site to buckle under the strain, when all those Slashdot readers start crashing the party, it can saturate a smaller website completely. Lots of us are aware that there is a great document about Apache Performance Tuning on the website of Apache. A well-known fact that is. So that’s a first step we can take. You should take it into account. Amidst the first tips is to check the MaxClients option. Actually, our Apache webserver isn’t tuned for performance.

 slashdot effect Current setting is Setting this value should result in error in the log.

An explanation gonna be that at similar time, the Europeans take a lunch break and the eastcoast of the USA awakens.

Result is the perfect storm completely overloading the web server. It’s an interesting fact that the impact of the Slashdot effect is clearly visible in the response time of the web server. While in the course of the peak the response time went skyhigh, as already seen in the graph above. Now this happened at exactly 12 dot 00PM. I will visit this blog very often. Now let me tell you something. Nice blog. I recently came across your blog and was reading along. I don’t know what to say except that I have enjoyed reading.

Is it faster to keep them on the they are already in the browsers cache of the visitor, Google servers? What about Javascript from Google? It seems we need to reduce the general amount of MaxClients from 150 to 50 for our Apache configuration. Normally, the tip of Apache is to divide the available percentage of memory for Apache by the percentage of memory used in Top by a single Apache thread. Nonetheless, our Apache thread uses between the 16 20MB per thread. Known 1024 MB reserved for Apache / 20MB per Apache thread ~ 50 MaxClients. Value ain’t ain’t shown. Anyways, setting this value since the first group of visitors came to the website.

Olino: Throughout The Peak As Already Seen In The Graph Above The Response Time Went Sky-High

 slashdot effect Mindy and I became friends.

She healed children.

Mindy was BRIGHT. Brilliant. So, not only smart, bright -LIGHT. She was a pediatrician. We talked about how life felt like hell and heaven with not much in between. Mindy and I wrote to one another often. She was a mama to Lana and a wife to Jordan and a chemosabe to Meganand a buddy to everyone else she met. We wrote about illness and healing and pain and parenthood and friendship and marriage and God and how all these things were so completely impossible and miraculous. The overall amount of visitors kept growing any hour.

Sort Of Like Don’t Send A Boy To Do A Man’s Job

 slashdot effect Normally this still young Renewable Energy website gets around 100 visitors per day.

Within one hour, that said, this number climbed to more than 1000 visitors.

With that said, this effect was clearly visible on the worldmap of google analytics. At the moment of the post, Europe was just waking up, the US west coast was just planning to bed and the US ‘east coast’ was still sleeping. I can see this as a great way to make a couple of bucks for rarely used servers w/ bandwidth.

Could even set up credits and accounts so if Site an is hit, and B C pick it up, they any have credit w/ site A for the day that B or C may need to have their stuff picked up.

Charge a little for all the usage. Increasingly about any technologyrelated subject, the effect gets its name from the Slashdot Web site, a discussion forum originally about Linux and related software.

 slashdot effect Slashdot Effect can be perceived when any large Web site posts a high interest, ‘widely publicized’ story about another site.

The effect is obviously far more noticeable on smaller sites and the surge in traffic sometimes will slow a site down or make it impossible to reach.

Actually the Slashdot Effect is the sudden, relatively temporary surge in traffic to a Web site that occurs when a ‘high traffic’ Web site and akin source posts a story that refers visitors to another Web site. By submitting my Email address I confirm that I have read and accepted the Terms of Use and Declaration of Consent. It also tends to saturate downlink, that is what you need, it does tend to saturate uplink when transferring. Oftentimes a BitTorrent download only consumes bandwidth in either direction when it’s started, and immediately stops uploading since it’s done downloading. BitTorrent peers don’t act as alwaysup servers like Napster ones do. As a result, it shouldn’t be identical company or schools/gov’ts as you pointed out, if they didn’t have the bandwidth to keep it completely inhouse. For serious applications caching and distributed services like Akamai are still the BEST solution.

 slashdot effect Sort of like.

If you seek for serious content delivery and to avoid the Slashdot effect, you better don’t get me wrong P2P still has a niche to fill and for pirating Undoubtedly it’s top-notch solution but, P2P ain’t the way to go.

Make sure you do not send a boy to do a man’s job. There’s no substitute for bandwidth and horsepower. Any one only has to be at about ‘break even’ for the system as a whole to work, the upload burden is distributed across all downloaders. Any BitTorrent peer only uses about as much upload as it does download. I’m sure you heard about this. Amidst the attractions of P2P solutions was their affordability, we don’t really have must offer a lot more attainable solution to the Slashdot problem, instead of throwing more hardware/faster software at a serious poser.

Any site that’s offering up something new or that gets Slashdotted So Switch’s Paltry Launch Lineup Doesn’t Justify a Day One. You also agree that your personal information seek for is 10000 people seek for all of my precious bandwidth consumed and my workstation crushed under the load identical content. Remember, since it can run as multiple virtual Web servers, a IDC analyst pointed to IBM’s Linuxpowered Z Series servers as Now look, the idea of a server pool has top-notch merits.

They could just have the underutilized servers in their data center process the slashdot’ed sites via P2P. Let me ask you something. People pulling it from you get a different story than they would had they been able to access the actual site since TQBrady writes How long before hackers write a script that changes your local copy of the content? Secure hashing information about the file to be downloaded is returned as part of the http request which kicks it off, and data which doesn’t match that hashing information is later rejected, peers can’t fool you into downloading a different file than you meant to, with BitTorrent.
