I don't know of a description, but you've nailed it. This reports the cumulative cpu time of processes running with a nice > 0. For the user, nice > 0 gets less CPU time than processes with nice of 0. Nice < 0 can only be set by root. Details on the behavior of nice depend on the scheduling algorithm. You can try asking on -hackers for information about that, or check the source yourself for the absolute truth. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
