Hmmm. Then if the scheduler is unaware of SMT, then even on a single-processor box SMT may degrade performance due to memory cache issues -- when two unrelated threads are executed in parallel, the effective size of the L1 and L2 caches is halved. With today's processor vs. DRAM speed difference, t

I think it's because Xeon processors use hyperthreading, which is sort of like a dual processor inside one processor (not really, but a bit like it). that allows instructions from separate threads to be processed at once by the same CPU in one cycle. You can read more about it here: http://arstechn
