hyperthreading off for SPEC Rate Base tests??? (Score 1)

Looking at pages 7 and 8 of the Veritest performance comparison quoted on Apple's website, I see that hyperthreading (HT) was turned off for the Intel P4 SPEC CPU2000 Rate Base testing. Am I missing something here? I wonder what the Intel benchmarks would have looked like with hyperthreading (HT) on?
