optimization guidelines...

[Olivier Bonvalet]

Hello,

if you use a wrapper for PHP with for exemple "export 
PHP_FCGI_CHILDREN=16", then the opcode cache will be shared between 16 
php instances.

If you have 4 or more CPU, you should try to use "xcache" instead of 
"apc" (and don't forget to adjust the xcache.count parameter), which 
give much better results for us (about 75% faster in high load).

Good luck,
Olivier
