title: Do I need memcached with Opcache ?
body: <p>I don't know anything about caching other than having read that people use APC/Opcache/Memcache/Memchached/Varnish ... to makes PHP go faster :) </p>
  
  <p>So, I tried APC last week since I was on PHP5.4, but then updated my to PHP5.5 so I could use Opcache. So, now that Opcache is working, I need to even make my wordpress site faster, and since I have heard that APC is not compatible with opcache, I would like to know if memcached is OK to use, as I am almost certain varnish is OK because it is not related to PHP. </p>
  
  <p>So, will using memcached further improve my site? </p>
