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… 2, 0, 1, 0 and 358.61

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… 1, 0, 0, 0 and 179.31
