Default Is it worth it to disable hyperthreading? - 06-17-2009, 01:49 PM

I've read that hyperthreading may actually HURT performance in some situations and with some non-XP operating systems (granted, that article is waay old and was refering to XP vs. Win2k).

So I'm wondering--has anyone running OSX played around with disabling hyperthreading and seen any performance changes?

Pentium 4 HyperThreading was terrible. I haven't tested it myself, but I believe the newer Atom and Nehalem/Core i7 implementations are alot better.

Since the atom does not support out of order execution, you really do want hyperthreading enabled.
