Windows Server Performance Tuning

I just came across this very good whitepaper on Windows 2008 Server performance tuning.  There is will be a lot of information that you already know, but you will probably learn some new things from this document.  There is quite a lot of information on storage, networking, processor utilisation and virtualisation.  The virtualisation section was most informative for me.

The document is in Word format http://msdn.microsoft.com/en-us/windows/hardware/gg463394
