    Default Performance in IE 7 and Mozilla Firefox (any version after 8.0)

    We developed an application purely based on ExtJS 4.0/4.1, it performs well in Mozilla Firefox(any version after 8.0). It is drastically slow in IE 7. Is it the issue with Ext JS framework?? or do we have any tools which determine why performance is slow in IE and not in Mozilla??

    Visit the The Ext JS Page Analyzer section of the Performance guide. The Page Analyzer provides a variety of metrics to help diagnose performance problem.
