SMP detection



I've read that SMP should be disabled for performance issues (I did not know
that before installing freebsd). I have a P4 3GHz with hyperthreading
technology. I have the SMP-GENERIC kernel and it only launches one cpu. So,
I've decided to disable SMP from BIOS. Is that ok?, knowing that I have a
Smp enabled kernel? or should I install one without smp? If so, is there a
way to install one already precompiled?
Thanks in advance
