This is a sudden revellation to you? :) Yes. The thing is, Microsoft is _specifically_ advertising Windows XP (which was used for this test) as 'HyperThreading optimized'.

This means that _right now_, there are severe issues with HT on a dual system. And they won't be resolved until a next generation of OS comes out. -- GCP
