      I'm not sure what you mean, so I might be wrong. My understanding of what you said is that with HT enabled, you can expect a 50% performance increase. That is unfortunately not true. I'm part of a research group that's using P4s with HT, and the most realistic speedup you get is under 10%.

      The problem with the chip is that eventhough two threads can have instructions executed simultaneously, they share everything. For example, if you run two floating point intensive applicaitons at the same time, they're both using the same floating point unit (units? I can't remember), which makes them basically sequential. Squeezing performance out of these is not easy.

      I have some experimental numbers in front of me where on a 4 way SMP where each processor is a P4 with HT. The difference with a particular application is that going from one thread to four makes a difference from 16.0s to about 5.3s. But then going from four to eight (using all HT contexts in the machine) makes a difference of 5.3s to 5.1s.
