You just need to open your eyes

	// ****** DATASTORE CACHE CONFIGURATION *****
	// Here you can configure different methods for caching datastore items.
	// vB_Datastore_Filecache  - to use includes/datastore/datastore_cache.php
	// vB_Datastore_APC - to use APC
	// vB_Datastore_XCache - to use XCache
	// vB_Datastore_Memcached - to use a Memcache server, more configuration below
$config['Datastore']['class'] = 'vB_Datastore_XCache';

	// ******** DATASTORE PREFIX ******
	// If you are using a PHP Caching system (APC, XCache, eAccelerator) with more
	// than one set of forums installed on your host, you *may* need to use a prefix
	// so that they do not try to use the same variable within the cache.
	// This works in a similar manner to the database table prefix.
$config['Datastore']['prefix'] = 'your_prefix';
