A performance note: I have one P4 w/hyperthreading. There are so many
things it does slower with HT on than off that I finally turned it off.
The biggest slow-up was calculating the my digital signature on my
email. I would have to dig out the specs on my cpu (it's an earlier
version) and do some hard timing tests, but a digital signature on a
short email would take 2-3 seconds with HT on and under 1 second with it
off. It may be a cache size issue that is causing the processor to
thrash.
