Does anyone know if leopard uses hyperthreading correctly? I tired searching for it to no avail.

 

I am running on a 3ghz prescott and I noticed Intel recommends disabling HT on windows 2000 despite it being multiprocessor capable. After turning it off as a test, my Xbench score jumped from 79 to 95. I am a bit curious as I thought leopard was built to use HT on the Mac Pro's Xenon's.

 

Thanks
