I have an Windows 2003 server with an IIS 6 website running on it. recently we have had a component developed in .NET4.0 and installed in a sub folder to the website. A new App Pool was created for .NET 4.0 and the app Pool was assigned to the .NET 4 sub folder. I might need to mention that the original website uses both .NET 2.0 an legacy-asp. The site is running with Integrated authentication Against AD.
Everything is running except the integration to the .NET 4.0 folder. When the application in the .NET 4.0 folder is called it takes at least 15 seconds for IIS to serve the Page. Regardless of whether it is the first request or the 100th request. The .NET 4.0 application is called from a Legacy ASP form with a Frame showing the ASP.NET 4.0 application.
We cannot touch the Legacy asp or ASP.NET 2.0 application as we do not own the rights to the software IE only have a usage license.
Any ideas on how to speed Things up would be appreciated.
