How to Configure APC Cache on Virtual Servers with PHP running under FCGId

By on November 8, 2010 in Wordpress

ndler .php5 IPCCommTimeout 12 </VirtualHost> You must “babysit” the configuration: use the APC monitor (apc.php) to see how many files are being cached, and how much memory (apc.shm_size) is needed to avoid fragmentation, which will cause the 500 errors. If fragmentation rises quickly to 100%, memory usage is full, and cache full count rises above 0, you will almost surely see “500″ errors. If WordPress is the only … 109, 1, 5, 0 and 218.06

WordPress with W3 Total Cache on Nginx with APC (Virtualmin)

By on March 12, 2012 in Web Server Performance Tuning, Wordpress

Virtualmin now includes support for Nginx web server. I deploy many WordPress sites with W3 Total Cache and APC Alternative PHP Cache, so I was very interested to see how Nginx performance compares to Apache for WordPress, and whether APC and W3TC would play nice with Nginx. I prefer to install WordPress in public_html/wordpress for ease of development, compatibility with other scripts, etc. Accordingly, the suggested configuration is for WordPr… 46, 1, 1, 0 and 84.71

APC Cache Considerations for Virtual Hosting Environments

By on August 22, 2011 in Wordpress

APC cache does not work well in a virtual hosting environment unless PHP is running as FCGID, and every individual virtual host has a unique PHP.ini and a unique fcgiwrapper. This is not the case with many virtual hosting environments because the memory and CPU requirements are too great. I suggest using Virtualmin for a shared hosting environment with APC cache, because it does allow to set php.ini and fcgiwrapper for every individual virtual h… 12, 1, 2, 0 and 26.98

Apache config for Worker MPM vs Prefork MPM

By on July 13, 2011 in Wordpress

Some installations of Apache will have been compiled to work with either Prefork or Worker MPM, but most by default are compiled only to work with Prefork. Changing to Worker MPM may allow your server to handle much higher traffic, more user sessions, with less RAM use. Your site or server will not scale well if it is running Prefork MPM. Worker is a bit more difficult to set up properly, and has some restrictions regarding functionality of PHP … 9, 1, 3, 0 and 19.68

Take Time to Get a Realistic Assessment of MySQL Performance If you have a PHP opcode and database caching strategy (such as APC) implemented on your web server and for your PHP script packages, you will be able to lower maxconnections, based on the information you receive from mysqltuner after 24-48 hours of steady traffic.

…the publisher after responding to a plea for assistance in a WordPress.org support forum. Though the site was running on a dedicated server with 8GB RAM, it was crashing frequently under load. The developer tried implementing APC Alternative PHP Cache and W3 Total Cache, but these measures turned out to be incompatible with some of the custom PHP code and the software architecture of the server. Haphazardly implementing randomly suggested “… 4, 1, 3, 0 and 13.05
