Randall Get the January issue of Linux magazine and turn to page 8. It fully describes how Redhat7.3 and later support hyperthreading out of the box. Also, hyperthreading technology started with the 2.0 chip. It increases processing speeds up to twice as fast as a dual processor and utilizes the L1 and L2 cache as well so don't buy into any negative comments about hyperthreading until you read the facts. Buy the way, the unit described in this article was a Dell and came preinstalled with RH7.2.

Now that I think about it, Red Hat 7.x after all updates uses the same kernel as Red Hat 8.0, a heavily patched 2.4.18, so even older 7.x releases can run hyperthreading now. Only difference with the 7.x kernel is that they are compiled with the old gcc 2.96 instead of gcc 3.2. But anyway, in most cases you wont notice much differences with hyperthreading enabled. A few specific optimized cases go faster with hyperthreading, but there's also a few cases where things actually can go SLOWER with hyperthreading due to one thread killing the L1 or L2 onchip cache used by the other.
