ASP.NET Interop benchmark in IIS 5.0

Hello,
I have an interesting finding, but I am quite confused.

I developed a simple asp.net web application that called COM dlls to loop through object collections via interop. In my development workstation (P4 2Ghz, XP, IIS 5.1), it took 1-2 seconds to complete the loop.

Then, I deployed it to server (Dual P3 1Ghz, W2k Server, IIS5.0), the performance was bad! It took 23 seconds to do the simple loop.

I have been looking for the causes for a while, no single answer. Any of you have any clues about what have happened?

Thanks million times.

It might be a config problem on the server. Make sure on the server that the ASPNET user has Admin rights
