title: How can I troubleshoot Rendering Performance issues in IE
body: <p>Our web application renders fast in some IE browsers, slow in others...  It seems to be an HTML rendering problem...  The first 10% of the page displays immediately, the last 90% takes up to 10 seconds, and this is static content.  I've run with firefox/yslow, renders very quickly.  Seems to be isolated to some users/configurations of ie.  Quirks mode does not seem to make a difference.</p>
  
  <p>Is there a tool or application that I can use to help me discover a rendering bottleneck?  Am I doing something egregious in my code?  Could it be a javascript issue?  Any help or suggestions will be much appreciated.  thanks.</p>
