Default Debian hyperthreading support

Pretty simple question really, does Debian i.e. the current Linux
Kernel handle hyperthreading well? I have a server running on an Intel
Atom D510, should I have HT enabled or disabled to get the best
performance?
Thanks.

Linux has handled hyperthreading since 2.4.x.

As for performance, see here [1] in general it doesn’t hurt performance,
but doesn’t help much either.

Sorry, the link was bad (for p4 hyperthreading) its late, my bad.

Reading more, it seems that with the atom, hyperthreading really helps
with parallel tasks, so I would leave it on.

I cant find any benchmarks of it on vs it off, and I dont have a spare
HDD to boot the atom330 I have to do some of my own.
