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 … 167, 3, 8, 0 and 309.19
WordPress with W3 Total Cache on Nginx with APC (Virtualmin)
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… 84, 2, 2, 0 and 146.07
APC Cache Considerations for Virtual Hosting Environments
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… 26, 2, 2, 0 and 49.94

Tuning Apache and MySQL for Best Performance in a Shared Virtual Hosting Environment
Web hosting has changed dramatically in the last few years. The majority of accounts are now running PHP scripts and MySQL, whereas in the past most accounts were only serving static HTML files. This presents challenges in security as well as performance tuning. It is impossible to predict whether a certain configuration will work properly for a given server, unless the hardware, software, accounts, network and traffic are identical to a previou… 16, 0, 2, 0 and 26.81

Punk Rock Music Community
Punktastic.com is a community powered site that covers punk music in Britain, but is poised to go worldwide. They cover punk and hardcore shows and festivals, and provide album reviews, video interviews and more. With a growing audience and user base, Punktastic needed a more reliable and robust web server, so they made the move to a dedicated CentOS 5 series web server with 3GB RAM. While this is a relatively low-end box, it has plenty of horse… 3, 0, 0, 0 and 4.68
Apache config for Worker MPM vs Prefork MPM
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 … 2, 0, 1, 0 and 3.66
