My web application is loading slowly in IE browser. I tried to test using Fiddler - we found out that there is a long delay between ClientBeginRequest and ClientDoneRequest, please refer to the test output of Fiddler -
In IE Browser: -
ClientConnected: 08:04:22.609
**ClientBeginRequest: 08:04:23.841**
GotRequestHeaders: 08:04:23.841
**ClientDoneRequest: 08:04:26.781**

ServerDoneResponse: 08:04:26.904
ClientBeginResponse: 08:04:26.904
ClientDoneResponse: 08:04:26.904
Overall Elapsed: 0:00:03.063
The same thing can be seen in the IE F12 Console as "Start Time"
Why is there a long delay between ClientBeginRequest and ClientDoneRequest in IE browser and how to improve it, the total time elapsed since the elapsed time is very large compared to the chrome result (see below).
