Iain,

So are you saying that a P4 is actually faster with HT disabled, or
simply that you don't have much to gain by using HT?  I've had a
dual-Xeon machine with 4 logical processors running Gentoo for a
couple years now, and I like being able to run 4 threads of
simulations at the same time.  The threads, when started nearly
simultaneously, seem to finish the same jobs in nearly the same amount
of time...  I've been told before that it's simply because the HT
makes both the actual processors less efficient...  Either way - I
haven't had any complaint about HT, but if there is conclusive
evidence that HT drastically takes away from true P4 power, then I'd
definitely like to know about it.

Thanks
Denis
