any specific requirements for APC's configuration ?
 

Im going to have APC installed because im about toi upgrade to 3.7.0

any specific requirements for APC's configuration ?

You will need to enable the use of APC in config.php.

Yes and no. There is no APC specific configuration needed. To get maximum benefit from it you should however store the datastore on the filesystem.

How do i do that?

Once APC is installed then there is a datastore option in vBulletin's "includes/config.php" file. Change this:

// ****** 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_Filecache';

To this:

// ****** 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_APC';

Sorry, my mistake. Forgot that option was added.

Im using this now and it seems to be alot better than the old one

Can we use two datastores at one time in cofig.php? Like memcache and xcache?

No you can't.

XCache has extra features that memcache lacks also.
