reduce priority of large port builds, e.g. firefox, gcc4x
Is it possible to reduce priority of port building processes with something like nice +19 make (tcsh syntax)? Here's a typical scenario for a large build (actually building gcc-4.7 and firefox in parallel): last pid: 54736; load averages: 5.27, 5.38, 5.11up 9+15:37:09 14:49:11 89 processes: 7 running, 79 sleeping, 2 zombie, 1 waiting CPU 0: 19.9% user, 46.3% nice, 33.8% system, 0.0% interrupt, 0.0% idle CPU 1: 15.4% user, 39.7% nice, 44.9% system, 0.0% interrupt, 0.0% idle Mem: 1141M Active, 3853M Inact, 1097M Wired, 128K Cache, 823M Buf, 1914M Free Swap: 13G Total, 16K Used, 13G Free PIDUIDTHR PRI NICE SIZERES STATE C TIME WCPU COMMAND 54720 0 1 89 10 111M 102M RUN 1 0:04 24.07% cc1plus 11 0 16 -76- 0K 512K WAIT0 26:55 11.33% intr 54732 0 1 85 10 87976K 77872K RUN 0 0:01 11.28% cc1plus 3289 1001 10 200 515M 387M uwait 0 163:26 3.47% firefox-bin 54721 1001 1 200 13656K 11744K CPU00 0:00 0.10% top 54731 0 1 49 10 14440K 12064K wait0 0:00 0.10% g++ 54736 0 1 520 11240K 9856K biowr 0 0:00 0.00% as 54734 0 1 420 12176K 10992K wait0 0:00 0.00% c++ 54735 0 1 720 17696K 11336K CPU11 0:00 0.00% cc1plus At such loads the system is noticeably slower. I'm not sure if nice has the same effect on all child processes, or only on the parent process? I'd like to set the make process and all its child processes to run only when there is some idle CPU. Is it feasible?

Is it feasible? why should the command 'nice ...' not work. It worked for me when I have had a single CPU machine without problems. The only difference was that I packed it into a script.

You may even want to make a shell alias in your cshrc, i.e. alias make nice +19 make (or something like it) signature.asc Description: OpenPGP digital signature

Sure, I do it all the time. ok, thanks. I'll try it next time.
