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

…roperly with apc.stat=0 because the config settings and files are dependent upon database and php, which will be cached as files or opcode. After you have sorted out your opcode settings, you may switch apc.stat=0 and restart the web server to turn off polling for better performance. If you cannot get APC to configured correctly for your WordPress sites, I suggest WP Super Cache and WP Minify… that combination will probably have a better ef… 24, 1, 2, 0 and 8458.06

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… 16, 1, 1, 0 and 4371.72

Tuning Apache and MySQL for Best Performance in a Shared Virtual Hosting Environment

…with max_connections set slightly higher than Apache’s maxclients. If you are running database caching via APC, you may lower max_connections, because APC will serve the busiest queries directly from cache. 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,… 32, 0, 1, 0 and 3554.45

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… 6, 1, 0, 0 and 1543.72

Apache and MySql Performance Tuning for High Traffic WordPress Website on Cpanel

…ning 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 Cpanel server. Haphazardly implementing randomly suggested “solutions” had actually made the problems worse, resulting in an “own goal” that brought… 8, 0, 0, 0 and 972.93

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.
