Hi > One more thing, I would request you to add default heuristics (number of > reclaimers), based on the number of cpus in the system.

I don't think so. all modern many cpu machine stand on NUMA. it mean following, - if cpu increases, then zone increases, too. if default value increase by #cpus, lock contension dramatically increase on large numa. Have I overlooked anything? and, (but) i afraid to 3 is too small value. if you have another test result on large machine, please show me. - kosaki -- 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/ | |||||||||
