It may be that the latency was advertised as so low that Windows
switched into C3 and back too often.
Also, the problem possibly wasn't SMP related but rather TPR related --
when the idle loop called acpi to do the mode switches, that caused many
tpr hits. Perhaps with a FlexPriority enabled processor it would work
better.
