Subject: Re: enabling hyper-threading on intel dual-core
Huge performance advantage and difference between i386 and amd64 kernel.
i386 is 32-bit and amd64 is obviously 64-bit, but
if you want dual core + ht
you gotta buy intel extream cpu ( dual core + ht = 4cpu)

You would need a Pentium Extreme (840, 955 or 965) for this. And
quite a bit of cash.

930 is perfect, fast enough, no need to spend more money, thanks :)

I think intel chips with dual core don't have hyperthreading. The
operating system sees the second core like it would with
hyperthreading only.

sysctl says:
machdep.cpu_idle_hlt: 0
is it right or i should see CPU 2 and 3 starting during the boot?
thanks for your help!
ps: i even compiled this option in ke
