It is not clear from the nice(1) man page, i.e. for /usr/bin/nice, not a shell built-in nice, what is the highest increment value nice will accept. It seems it is limited to 20. I tried $ /usr/bin/nice -n 100 portmaster -a But all processes spawned by the portmaster have the nice value of only 20, as in: PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 57586 root 1 52 20 13976K 4720K wait 0:00 0.39% sh 52729 root 1 40 20 13976K 4960K wait 0:02 0.00% sh 58239 root 1 92 20 35632K 8584K RUN 0:00 0.00% pkg 58237 root 1 52 20 9216K 1616K ppwait 0:00 0.00% make The root shell priority was 0. So is 20 the upper increment limit? Thanks Anton
