Which is better to enable php / mysql caching - xcache or memcache + memcached or all together?

Question

PHP

There is VPS OpenVz, ISP Manager lite and several WordPress sites. The content is standard Apache, nginx, mysql, php. Which one is more correct and, accordingly, more productive and hassle -free is better to do caching: Only xcache or memcache + memcached or all together?

Answer 1

If VPS, then I advise Memcached for object caching in WordPress and Batcache for page caching . For PHP bytecode caching, definitely APC.

Answer 2

FastCGI + Memcached + Opcache
