Hello!

You need this option/device in your KERNCONF file:
options 	SMP
device		apic

For better performance comment out SCHED_4BSD:
#options SCHED_4BSD
And take this:
options SCHED_ULE

You could also try these optimizations:
makeoptions     COPTFLAGS="-O2 -pipe -funroll-loops -ffast-math"

Normally it is but it depends on the load...
And more important than the number of CPUs could be the RAM...
