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