If anyone is interested in doing dirhash benchmarking then the thing to time is probably the system time of the opperation you are interested in. Also, doing: sysctl -w vfs.ufs.dirhash_docheck=0 before running the benchmark will turn off some debugging code in dirhash. Ian has just disabeled this by default in -curren and it will be disabeled in -stable shortly. David.
