jeff 2007-09-22 02:20:14 UTC FreeBSD src repository Modified files: sys/kern sched_ule.c Log: - Improve grammar. s/it's/its/. - Improve load long-term load balancer by always IPIing exactly once. Previously the delay after rebalancing could cause problems with uneven workloads. - Allow nice to have a linear effect on the interactivity score. This allows negatively niced programs to stay interactive longer. It may be useful with very expensive Xorg servers under high loads. In general it should not be necessary to alter the nice level to improve interactive response. We may also want to consider never allowing positively niced processes to become interactive at all. - Initialize ccpu to 0 rather than 0.0. The decimal point was leftover from when the code was copied from 4bsd. ccpu is 0 in ULE because ULE only exports weighted cpu values.
