Caching
APC (http://www.php.net/manual/en/intro.apc.php) is installed. It was installed with:

$ sudo pecl install apc

If you want to see what it installed and where, just do:

$ pecl list-files apc

Settings are in: /etc/php5/conf.d/apc.ini

To see APC status: http://neurocommons.org/apc.php

In neurocommons.org's LocalSettings.php.

$wgMainCacheType = CACHE_ACCEL;

Keep your eyes on the "Cache full count" under "File Cache Information". That number should be very low. You should probably considering bumping the apc.shm_size value in /etc/php5/conf.d/apc.ini until this counter levels off near zero. Creative Commons had to bump the apc.shm_size for the CC wiki and Teamspace to 192 and it sill has nearly used up all the memory and might be bumped again.

Our setting is currently 192M.

NathanKinkade is guru on these matter.
