Dear Staff,

Code: 
[config:server:epsr:lsphp4]'Process Limit' probably is too low, adjust the limit to: 310.

We played around with different opcode caches and now use :

PHP 5.3 : APC
PHP 5.4 : Opcache
PHP 5.5 : Opcache

We found Opcache to use fewer ressources than xcache.

If you want object cache, you could try Opcache + APCu
