since my site has gotten very busy and i have had a systems admin look over it he recommended to features to be installed and upgraded to accelerate php:
We'd instead recommend switching to a higher-performance PHP handler such as PHP-FPM. The FPM handler can also play very well with an opcode cache such as APC. We can make the appropriate installations for you.
also just curios - i had this removed since it was eating up a lot of my ram. i removed mod_perl from Apache but does xenforo need it? and does it improve xenforo in any way?
atm i have Xcache installed but unsure if that is useful for xenforo...
but is EAccelerator better then APC? can both of them work at the same time or only 1?
also since my site using a lot of bandwidth i would love to know if there is anything else i can have installed to reduce bandwidth usage but still keeping performance good on site..
also how good is xenforo with PHP 5.4 or 5.5? i don't want any issues ..
and what about the add ones made by third party for xenforo? do all add ones work for future version of php?
also same questions above but to do with Apache 2.4.7
if i wish to upgrade to that...
