    Hi

    On a forum i was wondering if the best solution is to use at the forum configs the memcache and leave the APC to cache the rest?

    Thank you

    yeah it does but APC Cache for data caching has high fragmentation of cache unlike Memcached for data caching

    Memcached always using less than 1 mb on a forum and yes i have been activated on the config file as ips wants ...

    I don't know if this is normal but seems to law if you compare it with APC usage at 70mb about :)

    Ok it is not too active forum but only 700kb about?

    yes because most forums don't utilise alot of data caching so memcached usage is low

    APC memory usage includes both php opcode cache + data cache, so opcode cached memory usage makes up majority for usage

    i believe @RoldanLT is talking about his Xenforo forums

    really depends on forum software and it's plugins/addons

    For vBulletin + vB Optimise Pro I have clients doing nearly 4,000 memcached requests/second and 10 billion cache hits per month with 200-600MB of cached data i.e. http://vbtechsupport.com/1526/

    Yes on my XenForo Forum.
    XenForo alone takes 300mb to 500MB of the cache and the rest is from ngx_pagespeed :)
