It also increases the size of NFSRVCACHE_HASHSIZE to 200. I haven't tested this at all, but I think putting all of the mutexes in an array like that is likely to cause cache-line ping-ponging. It may be better to use a pool mutex, or to put the mutexes adjacent in memory to the list heads that they protect. (But I probably won't be able to do the performance testing on any of these for a while. I have a server running the "drc2" code but haven't gotten my users to put a load on it yet.) -GAWollman _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
