It has always been said that hyperthreading should be disabled. I installed SW07SP4 on a Pentium 4, 3.4 GHz machine and downloaded Anna Wood's Punch Holder to benchmark it. With hyperthreading disabled the feature statistics total was 306 sec. I then enabled hyperthreading and was blown away when the feature statistics came in at 274 secs, and I watched the CPU ride at 100% as it blew through LPattern5.
It would appear that this SP4 release (and I want to run the test on 0.0) is more 'multithreaded' than previous versions. Can anyone else confirm on an earlier SP of 07 if enabling hyperthreading improves performance. I suspect this is a result of SW begining to tailor the app to take advantage of multicore processors. It seems that disabling hyperthreading is no longer the rule.
