Multithread SMT

Yeah so when you think you're having a 1.4 GHz CPU distributing available execution ports to waiting threads and where stalls are long, in fact you're really having eight 175 MHz processors working individually with stalls during the same in nanoseconds but not in cycles. It probably achieves higher total performance levels per transistor count but not in terms of peak performance. I better understand now why I was told gzip was ultra-slow on such machines.
