I have a 32 bit .net 2.0 application running under IIS7 on a 64 bit machine. Static content compression and dynamic contect compression are enabled. Everything works perfectly except the performance using IE6 and IE7 is extreamly slow. Some web pages
take up to 30 seconds to load in IE6 and 7. WIth Chrome or Firefox, the same page takes 5 seconds.
The Same application running under IIS6 has no performance issue with IE6 and 7.
Has anyone experienced this or has anyone suggestions on how I can improve IE6 and 7 performace with IIS7.5?

I suggest you check Eric Laws IE MSDN blog
This IIS Net Forum Thread http://forums.iis.net/t/1180411.aspx
For IE if you have the Developer Tool Bar use the F-12 Key and check compatiablity modes.

As you say the issues are with IE Browsers but there maybe other considerations.
You should start by working with references and tests. I suggest get (Homer)

Wcat http://www.iis.net/community/default.aspx?tabid=34&g=6&i=1467 .
Run the Stress Tests for the browsers Opera FireFox and the IE 6 7 8 as the base line. Then check the Web Sites for Cache and Compression.
Then check the Web Sites for Browsers IE 6 7 8 for compatiblity mode in the Browser and in IIS Server using the UA meta tags.
You might get Log Parser to look at the requests and Timing in the IIS Server logs.

Look at Log Parser "Deciphering Log Parser logs"
you install the Office Web Componenets and get charts etc.

I suspect something to do with eth compression but look in the failed request tracing for where the delay occurs.
