Also you can use Fiddler to look at the http responses from a client prespective to see if you can capture the 400/500 errors. You can even see which script or url sequence is taking the longest as it looks from the client, and reissue that request after you make changes to see if the performance is helping.
Also need to hook up filemon and regmon to the W3wp.exe process that is running in the web application pool(s) that are running under the website. Also look at any issues with the backend database if you are using one for the website, which might be your problem if you are dealing with locking/blocking or slow website performance due to DB issues. Also the stuff at Ken's site (IISSTATE and others will prove useful) Are you seeing any specific errors in the IIS logs ( like 400.X or 500.x) or the httperr.log (Look at http://msdn.microsoft.com/en-us/library/aa954365.aspx) Z Edward Ziots Network Engineer Lifespan Organization MCSE,MCSA,MCP+I, ME, CCA, Security +, Network + [email protected] Phone:401-639-3505 ________________________________ From: Michael B.

Performance issue on website response. Server literally takes 20-30 seconds to response to request sent by the firewall before firewall forwards response to user on the Interwebs. Mucho time spent with wireshark analyzing packet traces to show that the firewall is receiving the request from the WAN and promptly forwards http request to internal web server. Web server response takes forever to respond, troubleshooting now but wanted to throw this out to the collective...
