my own spur of the moment benchmarks: writes at 88-95MB/sec, reads at 69-76MB/sec
this is NFSv3 to a 960, over a gigE link. This filer was doing some other stuff, so you could probably squeeze another couple MB/sec out under ideal conditions.
the second test is a 16GB file, cause I wanted to see how performance degraded once you overflowed the NetApp cache...
