Does anyone have experience running SilkPerformer on Windows Server 2003?

I currently have a lab setup with multiple machines for SilkPerformer load generation. They run Windows 2000 Server and I have had no problems. We are about to setup a new environment for SilkPerformer. My question is, should I move to Windows Server 2003? Does anyone have experience that can comment on scalability and performance of SilkPerformer on Server 2003 vs. Win2k or other versions of Windows (especially on multi-CPU systems).

Any suggestions, comments, or discussion on anything related is appreciated.
