title: Wordpress Caching Plugins - When Should I Use Them?
body: <p>In the past two months I have had a site of mine really take off (at least in my mind) and get around 2600 uniques, and 10,000 pages views a month.  I'm on a VPS that performs pretty well, but I have experimented with the W3 Total Cache Wordpress plugin, as well as using CloudFlare.  I really struggle in being able to tell if I get much overall performance improvement from these plugins and services.</p>
  
  <p>My question is, when should I really be using a caching service?  Is there a certain traffic level that makes these plugins or services make sense?</p>
