How can you speed up your ASP .NET application in the Production Environment?

After you finish your ASP .NET Application "Developing and Testing", and before you upload the application to a production server, don't forget to change the value of debug="true" to false in the compilation section in the Web.Config file.

This would increase the performance of your application.
