title: Heavy Javascript page gap of 15 seconds between response and page load
body: <p>I have a page (A) which is a heavy javascript page, when I leave this page to go to page B it takes a long time. When I go to page B from a different page it is really fast. So it has something to do with page A and probably its javascript. </p>
  
  <p>When I run the network profiler from the developer tools in IE 9 it shows a gap of ~15 seconds  between the response and the DomContentLoaded(event). </p>
  
  <p>Page A is heavy with javascript because it runs the Xopus Editor, a rich text XML editor. </p>
  
  <p>Does anybody have any ideas on what I could do to either analyse the gap as to what happens or what I could do to make Page A unload faster. </p>
