I have a webpage (ASP.NET 4.0 / MVC 4).
On my development machine (i5-2500 3.3 8GB Win7 VS2010 SP1 Fujitsu Esprimo P700) the page performs with 160 requests/sec on devenv webserver on my machine. The page performs with 250 requests/sec on my local IIS 7.5. (uncompiled web)
The page performs with 20 requests per second on a 16core 32gb ram production server (Fujitsu RX-300 w2k8 rc2 IIS 7.5). (compiled web)
Why? I think it's the IIS configuration but i can't figure out whats the problem. The page runs with 1 worker process on both machines. Web garden is not an option (it helps but the app isnt compatible with)
EDIT:
The driver versions of http.sys and tcpip.sys are same on prod and dev. The tests were always run on the machines itsself on localhost. The CPU usage on prod is 95% @ 20 req. On dev 80% @ 250 req. (32 threads) there is no db or io involved in this test. I opened the server, and yes there are really 16 xeon cores inside on prod.

You need to use more CPUs on the given IIS worker - check out the advanced settings. And the benchmark you need to run with multiple connections (like twice the number of cores).

This may sound ridiculous, but try running IIS in 32bit mode, i know situation, when this helped to reduce CPU consumption by 50%.

I solved the Problem.
The 12 Cores made the server slow. I ran 1 instance of w2k8 r2 on the system. If i put 6 virtual w2k8r2 machines with 2 cores each the situation is completely different.
