WordPress.com is the cloud version of WordPress that is hosted and supported by Automattic. WordPress.com serves more than 33 million sites attracting over 339 million people and 3.4 billion pages each month. Since April 2008, WordPress.com has experienced about 4.4 times growth in page views. WordPress.com VIP hosts many popular sites including CNN’s Political Ticker, NFL, Time Inc’s The Page, People Magazine’s Style Watch, corporate blogs for Flickr and KROQ, and many more. Automattic operates two thousand servers in twelve, globally distributed, data centers. WordPress.com customer data is instantly replicated between different locations to provide an extremely reliable and fast web experience for hundreds of millions of visitors. Problem WordPress.com, which began in 2005, started on shared hosting, much like all of the WordPress.org sites. It was soon moved to a single dedicated server and then to two servers. In late 2005, WordPress.com opened to the public and by early 2006 had expanded to four web servers, with traffic being distributed using round robin DNS. Soon thereafter WordPress.com expanded to a second data center and then to a third. It quickly became apparent that round robin DNS wasn’t a viable long-term solution. While hardware appliances like F5 BIG-IP’s offered many features that WordPress.com required, Automattic decided to evaluate different options built on existing open source software. Using open source software on commodity hardware provides the ultimate level of flexibility and also comes with a cost savings “Purchasing a pair of capable hardware appliances in a failover configuration for a single datacenter may be a little expensive, but purchasing and servicing 10 sets for 10 data centers soon becomes very expensive.” At first, the WordPress.com team chose Pound as a software load balancer because of its ease of use and built-in SSL support. After using Pound for about two years, WordPress.com required additional functionality and scalability, namely: On-the-fly reconfiguration capabilities, without interrupting live traffic. Better health check mechanisms, allowing to smoothly and gradually recover from a backend failure, without overloading application infrastructure with unexpected load of requests. Better scalability both requests per second, and the number of concurrent connections. Pound’s thread-based model wasn’t able to reliably handle over 1,000 requests per second per load balancing instance. Solution In April 2008 Automattic converted all WordPress.com load balancers from Pound to NGINX. Before that Automattic engineers had been using NGINX for Gravatar for a few months and were impressed by its performance and scalability, so moving WordPress.com over was the natural next step. Before switching WordPress.com to NGINX, Automattic evaluated several other products, including HAProxy, and LVS. Here are some of the reasons why NGINX was chosen: Easy, flexible and logical configuration. Ability to reconfigure and upgrade NGINX instances on-the-fly, without dropping user requests. Application request routing via FastCGI, uwsgi or SCGI protocols; NGINX can also serve static content directly from storage for additional performance optimization. The only software tested that was capable of reliably handling over 10,000 request per second of live traffic to WordPress applications from a single server. NGINX’s memory and CPU footprints are minimal, and predictable. After switching to NGINX the CPU usage on the load balancing servers dropped three times. Today in 2012, WordPress.com is serving an average of 70,000 req/sec and over 15 Gbit/sec of traffic from its 36 NGINX powered load balancers, with plenty of room to grow. Most of NGINX load balancers serve about 5,000 req/sec, sometimes peaking to 20,000 req/s, and have about 50,000 established connections. Typical hardware configuration is Dual Xeon 5620 8 core CPUs with hyper-threading, 8-12GB of RAM, running Debian Linux 6.0. As part of high availability setup WordPress.com previously used Wackamole/Spread but has recently started to migrate to Keepalived. Even distribution of inbound requests across NGINX-based web acceleration and load balancing layer is based on DNS round-robin mechanism. Following a successful deployment of NGINX as web acceleration, load balancing and traffic management solution, WordPress.com recently completed migration from Litespeed to NGINX across all application backend servers. NGINX combined with the FastCGI Process Manager (FPM) for PHP allows greater control, easier configuration, and no additional maintenance overhead for the 5-member Automattic Systems Team.

  Now, by all means, if you can make this better, leave me some comments with your suggestions, and as I figure out better ways to do this, I will post them here. Have fun coding! ~Kevin Read the full article

Hey folks time for another quick article to get your ModX site running tip-top.    This one will allow you to 'prefetch' your sites pages for a faster browsing experience.   Now ModX has a pretty fantastic caching mechanism already built in, but I find that if your site has a lot of pages, sometimes that can take a bit on the initial load. This will take care of that issue. First and fore-most you will need to make sure to include the latest jQuery library in your templates.  This can be found at: jquery.com Next you will need to create a php file inside your 'wp-content' folder.   I usually create a few default folders inside this... one happens to be called 'php' Once you have the file created, remember what the file is, and add this code to it:   Now, once you've got this page created, insert the following tag at the bottom of your template.    You should already be including your script files down here anyways (see here) As you can see, I've named mine 'prefetched.php', just rename this file and path to where you have yours located at. Using FireBug in FireFox you can see these pages getting 'fetched', and when you browse to them you'll notice that they load a bit faster than they did before, this is because they are now primed in your browsers cache. UPDATE:  You can also help this along by using HTML5's built-in prefetcher! Create a snippet with the following code: Read the full article
