Settings for XCache using vB5

[kuntur]

I will appreciate if someone could help me. I have XCache installed on a dedicated server

GenuineIntel, Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz
CentOS 6.5
mysql 5.5.36-21
php 5.4.25-31

I am upgrading from vB 4.2.2 to vB 5.0.5 and I would like to know if the following settings in my core config.php are correct

   // ****** CACHE CONFIGURATION *****
    // Here you can configure different methods for caching items.
    // The following are the cacheing classes that can be used.
    // vB_Cache_Db - This setting stores the data in the database
    // vB_Cache_APC - This setting stores the data in APC
    // vB_Cache_Memcached - This stores the data in memcache
    // vB_Cache_Memory - This setting uses php's memory while a page is being generated.
    // Each cache area can use its own cache type.
$config['Cache']['class'][0] = 'vB_Cache_XCache'; //regular cache
$config['Cache']['class'][1] = 'vB_Cache_Memory'; //fastest cache
$config['Cache']['class'][2] = 'vB_Cache_Db'; //largest cache and longest life.

//	Cache options are
// 		vB_Cache_Memory			fastest but doesn't survive a page load.
//		vB_Cache_Db				significant speed improvement and available to everyone.
//		vB_Cache_Filesystem		good performance, reduces traffic and load on db server. Not available to everyone-
//								your web server must be able to write to the file system.
//		vB_Cache_Memcached		excellent performance but usually only available to dedicated or virtual hosted sites.
//		vB_Cache_APC			excellent performance but only available to those with APC installed, and on a single web server.
//		vB_Cache_XCache			excellent performance but only available to those with XCache installed, and on a single web server.

//	******** FILESYSTEM CACHE CONFIGURATION ******
//If you use filesystem cache you MUST uncomment the line below.
//set the path to somewher writeable by the web server process. This location must already exist. Please put
// this somewhere outside the document root. Otherwise you have just created a serious security issue.
//Don't include the final '/'

//$config['Cache']['fileCachePath'] = '/valid/writeable/for/my/webserver';


	// ****** DATASTORE CACHE CONFIGURATION *****
	// Here you can configure different methods for caching datastore items.
	// You may need to clear this cache after installing/upgrading. You can do this either
	// in the control panel (Maintenance) or by restarting the web server.
	// vB_Datastore_Filecache  - to use includes/datastore/datastore_cache.php
	// vB_Datastore_APC - to use APC
	// vB_Datastore_XCache - to use XCache
	// vB_Datastore_WinCache - to use WinCache
	// vB_Datastore_Memcached - to use a Memcache server, more configuration below
$config['Datastore']['class'] = 'vB_Datastore_XCache';
	//if you use Filecache you can accept the default location, or better
	// to uncomment the next line and set a location
	// $config['Misc']['datastorepath'] = '/valid/writeable/for/my/webserver';
	// or if you have set $config['Cache']['fileCachePath' above you can do nothing and
	// it will use that location.

    // ******** DATASTORE PREFIX ******
    // If you are using a PHP Caching system (APC, XCache, eAccelerator, WinCache) 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'] = 'DP1_';
