The OpenBSD 4.9 release announcement says
"SMP kernels can now boot on machines with up to 64 cores;"
So OpenBSD does support several CPU's/cores?
If i have a Core2Duo cpu in my laptop (t7100) then would it bring greater performance if I use "SMP" kernel?
If this is true, then how can I install/use an SMP kernel under OpenBSD 4.9?

SMP has been supported since OpenBSD 3.6, released in 2004.
Presumably the old limit was 4 cores or 16 cores.
The easiest way to get SMP support is to install the
bsd.mp
kernel. That should happen by default if your system has multiple cores.OpenBSD SMP project
