Con, As a result of the patch "sched:dont decrease idle sleep avg" introduced after 2.6.15, there is a 4% drop in Volanomark throughput on our Itanium test machine. Probably the following happened: Compared to previous code, this patch slightly increases the the priority boost when a job is woken up. This adds priority spread and variations to the wait time of jobs on run queue if we have a lot of similar jobs in the system. See patch: http://www.kernel.org/git/? p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e72ff0bb2c163eb13014ba113701bd42dab382fe Regards, Tim - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
