Over half a billion NFS ops per day, so we roll the uptime ops counter about once a week...

Holy schmoley. What's your response time, a few minutes? ;)
Until next time...

Officially, ~7000 ops/sec according to SPEC SF. This number will vary depending on the type of operations being performed. I myself have seen one of my filers running 18,000 NFS/sec for four weeks straight during simulation runs. This is possible given the nature of the application running the simulation and the type of opperations being performed.
file lookups and get attributes do not take long and many may be performed in short times.
Check out http://www.spec.org for information on how ratings are done.

If Solaris 2.6's iostat is trustworthy for NFS, the filers (there are two like that, clustered) are still doing better than the internal disk. ;-)

This is averaged, of course... right now the filers are "only" doing about 7500 NFS/ops (low traffic time... 7:50 pm here). I'll check again tomorrow during business hours. Not sure why /local-vs2.6 stands out... that's just a shared /usr/local filesystem. The /www* mounts get hammered the most.
