Actually I based it on data that Dr. Hyatt posted previously. The data Vincent
has for his program doesn't show such wonderful gains. That's nice. It's not
representative of everything, and it's not even conclusive. Truth is, Vincent's
data doesn't show jack. You need multiple tests and multiple machines to show
anything conclusively.

Ok, it's been optimized for Pentium 4, which is -almost- the same thing. If it
runs well on P4, it runs well with HT because it will fall into an I/O burst
cycle. He has stated a number of times that his interests are in the P4 because
he has one on his desk. Eugene's interests are obviously in the P4. It's not
rocket science to figure out what that means.
