Thanks everyone for the comments. BTW, this is only a minimal SMP system 
(2 way Opteron), so not sure whether it'd make much difference anyway. 
using 4BSD for now until I have some real-world apps running in order to 
test.

btw, any chance of other schedulers being added to fbsd, like the 
staircase sched found in linux , or maybe others? (not offering as I 
can't code @ that level, just curious)

thanks again,
