Poor XML WS performance on Windows 2003

I have a web service that does some heavy lifting with XML and hash tables.
I moved my architecture to Windows 2003 (5 identical servers behind a load
balancer, 1 stayed on Windows 2000), and now have a major performance
problem. The Win2k3 servers are running at an average of 7.7s/call, and the
Win 2000 runs at 2.6s/call. I broke my logging in 4 parts, and the more XML
or XSL the part has, the more apparent the differnce in run time.

Has anyone else seen similar results?

Surely this will depend on exactly what you're doing in the web service?

You should profile it and see what it's doing. I've started evaluating
JetBrains' "dotTrace" product, and it's shown me some amazing things, like
how long XmlDocument.Load takes, and how much overhead is involved with XML
Serialization. Take a look and see what you see.

YourKit .NET Profiler http://www.yourkit.com is also very good
