Question : IIS 6.0 asp.net 2.0 cpu performance issue

We have an asp.net sql server app that runs great on our dev server.  We are doing  performance testing and on our dev server we can get up to 30 users running just fine.  This is a Windows Server datacenter Cloud machine with 1 GB RAM and iis 7.0 and sql server express 2008.

We have a production server with nothing running on it.  It is Windows 2003 R2 Enterprise Edition  SP2  IIS6.0 Sql Server Express 2008.  It has 4 GB RAM on it.  We copied our application there.  We can't get 10 users running concurrently without hitting 100 cpu utilization.  It looks like w3wp.exe is what's using most of the cpu cycles.

Both machines are 2GHz Intel Xeon CPU machines running in a Virtual environment.

What can we do to tune our production machine?

Hey d2fox.
Sorry for not posting anything on this issue for over a week.

I found this ASP.net BPA
Can you run this utility and see what results you get.
