Hi
I don't think so.
How about adding something like..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? == CONFIG_SIMULTANEOUS_PAGE_RECLAIMERS int default 3 depends on DEBUG help This value determines the number of threads which can do page reclaim in a zone simultaneously. If this is too big, performance under heavy memory pressure will decrease. If unsure, use default. == Then, you can get performance reports from people interested in this feature in test cycle. hm, intersting. but sysctl parameter is more better, i think. OK, I'll add it at next post. I think sysctl should be interesting. The config option provides good documentation, but it is static in nature (requires reboot to change). I wish we could have the best of both worlds. -- Warm Regards, Balbir Singh Linux Technology Center IBM, ISTL | ||||||||||
