Alergic on "W3 Total Cache: can't diasble "Use late init""

I just changed the setting for Page Cache, from Disk Enhanced to Opcode: xcache.
There are people here that says this is not the recommended setting for
'Shared Servers', but now I finally can disable 'Use late init'.
Need more tests on Google Page Speed, to check for delayed server response (like it was until now). And of course, the stats in cPanel, maybe I will notice some decrease of performance due to Opcode:xCache.
