Yup, I got DOCUMENTED proof. Exploit info: http://www.daemonology.net/papers/htt.pdf

Long document short, there's a way to mess with the Cache and hijack admin stuff. Really serious, but I'm no deep core techie so I don't know the true depth of it. But I know it poses serious issues to servers.

Barton Core vs HT. (Google it)

Evidently the Barton Core doesn't handle 4 threads as I was told, some guy at a computer store. Grr, I ought to hit him with one of the wiffle bats... (Serves me right for not checking up on that) But the dual core stuff coming out now is good enough. But Hyperthreading DOES slow down servers apparantly.
