I'm currently running vB 4.03 Suite (with CMS & Blogs disabled) on a Servint Essential VPS (768mb Guaranteed RAM) running with XCache. I also run a single copy of Wordpress on this server. Next week I'm hoping to complete an upgrade to xF 1.1.1, so I'm trying to figure our what server configuration to set for xF. I read the manual, and that has suggested settings for APC and memcache. http://xenforo.com/help/cache/ I also saw a post where Kier suggested (and I hope I understood him correctly) to install APC or memcache for shared memory caching, but only configure memcache in the config.php file. http://xenforo.com/community/threads/tip-use-apc.6456/page-4#post-237629 I also read that someone came up with a configuration that works for XCache, but no-one has confirmed if it works... http://xenforo.com/community/threads/xcache-for-xenforo.23036/ So I guess my question is, with all these choices, what will work best for my site? Do I stick to XCache and try to make it work, or contact my techs and replace XCache with APC, or Memcache? I'm not a server tech, but I'm leaning towards switching my server to Memcache, but I don't know if that's the right move to make. Any suggestions?
