Linus agrees with you. Linus is usually right. There was a long drawn out thread on lkml a while back about this in regard to process schedulers and this dodge/hack kept coming up. Linus' point was that it does very little, upsets the kernel's view of how to schedule jobs and he had numbers to back it up. Most interesting was his assertion that niceness usually has very little effect on Linux anyway - most differences noted are placebo effects - and niceness comes from the days 30 years ago when Unix kernels were not smart about scheduling. And niceness was only ever a kernel hint anyway. I haven't seen any patches that might affect this since so I reckon it still produces precious little effect. -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
