title: Memcached vs APC which one should I choose?
body: <p>I read this article: <a href="http://www.mysqlperformanceblog.com/2006/09/27/apc-or-memcached/" rel="noreferrer">http://www.mysqlperformanceblog.com/2006/09/27/apc-or-memcached/</a> from way back when.. I want to get the best caching engine available so that my application is really fast. Of course I don't want to over-cache but I want to at least choose the best thing out there. In that article it says Memcached is slow and apc is fast so why is everyone choosing <a href="http://en.wikipedia.org/wiki/Memcache" rel="noreferrer">memcached</a>?</p>
  
  <p><a href="http://framework.zend.com/manual/en/zend.cache.backends.html#zend.cache.backends.twolevels" rel="noreferrer">http://framework.zend.com/manual/en/zend.cache.backends.html#zend.cache.backends.twolevels</a> here is says "use a fast one (but limited) like Apc, Memcache... and a "slow" one like File, Sqlite..." do you think using Apc as the fast and Memcache as the slow is a good idea?</p>
