At this point, Intel's Hyperthreading > (again, generically called Simultaneous Multithreading, or SMT) is nothing > more than marketing hype. As Intel plainly states, Linux does not support > it, nor do any of MS's current server OSs. ah, not quite true Linux as of kernel 2.4.18 supports HT The biggest advantage that HT would give would be better allocation of resources when dealing with something like IDE overhead (a large matter of contention in this list) In some SMP aware applications, the second chip almost doubles the performance, HT merely ups that by around 20-30%.
