Hyper-Threading means: There is one core with two execution paths, which means some of the common CPU features, but not all, are present twice. As I remember: Under some circumstances, there were some percent performance boost. But mostly there was more a performace loss if one enables hyperthreading on a P4. That may be the reason for having disabled the hyperthreading in the BIOS. Things may have changed with more up-to-date INTEL hyperthreading CPUs...
