XCache
XenServ's PHP powered hosting almost always comes with that awesome XCache.
You may find XCache may not function properly with your IP.Board depending on it's version, modules, etc. It's a hit or miss however it's the fastest cache method.
Open conf_global.php in your forum root
Add
$INFO['use_xcache'] = 1;
Memcached
Ever hear about MemCached? IP.Board 2.2 and higher now has a API for it.
XenServ provides client's free access to Memcache daemons.
How to apply into IP.Board?
Open conf_global.php in your forum root.
