Looks to me like you need spin counts on your mutexs. Either use a
spincounting critical section, or else use QMutex from TnFOX
(http://www.nedprod.com/TnFOX/). You will find QMutex is several
dozen times faster than anything windows provides for you (and the
version in SVN even works on all architectures, though it's much
faster on x86 or x64).
Cheers,
