As far as I see, SCHED_ULE scheduler doesn't take advantage of having more
than 1 processor.
During make -j 6 buildworld, and other process that consumes as much of
computing power as he can, I get such output from top:
CPU states: 36.0% user, 0.0% nice, 13.8% system, 2.5% interrupt, 47.7% idle
Is it natural for this scheduler?
Dmesg attached.
