Hi! Is idprio(1) broken in stable/11?
As root, start one bzip2 instance with idprio and one additional bzip2 intance per CPU core: # idprio 5 bzip2 -9 </dev/zero >/dev/null & # n=$(sysctl -n kern.smp.cpus) # i=1; while [ $i -le $n ]; do bzip2 -9 </dev/zero >/dev/null & i=$(($i+1)); done # top For dual core system, I see that idprio'd bzip2 takes all cycles of first core and two "normal" bzip2's share cycles of second core each taking ~50% of CPU time. It is expected that idprio'd bzip2 get no CPU time at all and each of "normal" bzip2's get ~100% of single CPU core for such setup.
