title: Timing with the Firebug Net Panel: What is the onload time?
body: <p>I'm using the Firebug net panel to see response times. On the net panel's status bar, the summary is displayed as follows:</p>
  
  <p><strong>
  10 requests &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 90KB&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 10.22s (onload 6.57s)
  </strong></p>
  
  <p>What does that onload time mean? Does it mean that once the content was received from the server, it took another 6.57 seconds for the page to become usable (i.e. for the onready event to finish)?</p>
  
  <p>Note: The site I'm testing is VERY heavy with Qooxdoo components and oodles of JavaScript.</p>
