thank you for the reply.
I have still phpbb v3.0.5 i know i should upgrade it to 3.0.6 but for the moment i have to stick with v3.0.5.
my site is experiencing overloading which are caused mainly by viewforum and viewtopic
I'm looking on a way to reduce this server overload.
from what i understood you recommend using the opcode cache to reduce server overload.
can you please explain more on how to enable it?
changing the value of $acm_type in config.php
thank you both for your support and sorry for my ignorance.
note that from what i read above i wont use eAccelerator?
