APC Cache Considerations for Virtual Hosting Environments

By on August 22, 2011 in Consulting, Virtualmin, Web Server Performance Tuning, Wordpress

…almin for a shared hosting environment with APC cache, because it does allow to set php.ini and fcgiwrapper for every individual virtual host, and so to set an individual configuration for APC per virtual server. However with 200+ virtual hosts all running PHP script packages, as is the case with a commodity shared hosting server, this will use a lot of memory, and you will need somewhere in the neighborhood of 10-30GB apc.shm_size if you attempt… 11, 1, 1, 0 and 1363.11

SSL and CloudFront CDN Support for WebFonts via .htaccess

By on September 5, 2012 in Amazon Web Services, Wordpress

I recently upgraded my WordPress theme to WooThemes Canvas 5.x, and I found that some of the icons were not rendering, but were showing a letter or integer instead. I dug into the code and found that these icons are now delivered via @font-face webfonts. Meanwhile, I’m working on a client’s e-commerce site with Google WebFonts and a custom webfont to display the Rupee symbol (Indian currency). Though the fonts were uploading properly… 3, 0, 0, 0 and 143.49

Apache config for Worker MPM vs Prefork MPM

By on July 13, 2011 in Consulting, Web Server Performance Tuning, 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… 2, 0, 0, 0 and 95.66
