Okay, so my host has xcache installed for PHP acceleration, and its default setting is 16mb of memory for the opcode cache (I'm not using the variable cache for now).
I'm just wondering how large the opcode cache should be for a typical phpBB installation, in order to be able to cache all scripts?
I know that this is what xcache admin is for, but I don't believe my hosting provider includes it, which means I'd have to compile my own version of PHP (since I can't add extensions either, at least not easily).
So yeah, just hoping someone out there with xcache enabled can give me an idea of how much memory they think their phpBB3 installation needs for best performance? i.e - if I'm not running much else, then is 16mb adequate, is more always better, or is it overkill?
