Nah, Daniel is right. Even non-SMP programs do gain a slight advantage in speed with HT enabled, though minimal, benchmarks have shown this. I have no evidence to support this, but if I were to take a guess, I'd say that HT doesn't so much help the program in question run faster, but it does make management of all the other processes that are running easier for the OS, leaving more CPU time for the program. Again, just a theory. I'm currently in the middle of running a private tournament on my box, but I will be able to give it a rest in an hour or two to try this position out.
