title: Benchmarking Zend Framework with a plugin
body: <p>I have created this plugin to benchmark the performance of my Zend Framework Project</p>
  
  <p><a href="http://pastebin.com/HD9MpRfR" rel="nofollow">http://pastebin.com/HD9MpRfR</a></p>
  
  <p>One odd thing that happens is that sometimes the generated values are negative, </p>
  
  <pre><code>Unit: Microseconds 
  Routing: 0.0013879999999999 
  Dispatch : -0.477942 
  Dispatch Loop: -0.470018 
  Total : -0.430279 
  </code></pre>
  
  <p>Why is this?</p>
