Question : Extremely slow performance on Web Application

Hi,

We are running an ASP.NET Web application on an IIS7 Web Server with a SQL Server 2008 database backend.  About 3 days ago, we received an error on the web application saying 'Maximum request length exceeded'.  On troubleshooting this error, we found that we needed to increase the maxrequestlength property in our web.config file.  We did that and realised that the error disappeared. However, there was a significant drop in the performance. We've been troubleshooting both the SQL server and the IIS to find out where the bottle neck is. We have other applications accessing the SQL server and they seem to be fine which is why we have reason to believe that the problem is with the web application.  We have removed and deployed older versions of the application and still no difference which leads us to believe that it is an IIS problem and not a code problem in our application.  

Can anyone advise on causes of delays in request and response times between IIS and SQL Server?

Your assistance will be greatly appreciated.

Thanks

Answer : Extremely slow performance on Web Application

Thank you all for your help. We later found out the problem. the ASP application that we built was using data bindings which loads about 200,000 records everytime a user searches for a record. We disabled it and everything else turns out to be fine.
Thank you all
