So if a CPU is running with hyperthreading enabled its speed won't be equal to the speed without hyperthreading enabled due to the speed using multiple processors not being additive? Or am I just using screwed up logic?
Im slightly confused and since ive not slept in 42 hours im not gonna try and think too hard ... but if you're only dealing with one thread there is somewhat of an overhead invovled (think of it as a hardware listener for new threads but since there is never a new thread, that listening acts as a minor overhead). Now if you're doing multithreaded ops than it should work as intended.
