[TYPO3-english] XCache Version: 3.1.0 vsOPcache for typo3 6.2

[TSniper]

Hello,

I have a slow performance at typo3 BE, i want to know what is the better to use to get higher performance on installation :
PHP Version 5.4.26.

I have this message on the isntall tool : 
A PHP opcode cache is loaded
Name: XCache Version: 3.1.0
This opcode cache may work correctly but has medium performance.

Should i use OPcache instead of XCache ? is it necessary to get a good performance on my typo3 BE ?

Thnak you:
