How many ops/second can the F760 handle?
It depends on the mix of read/write ops you are doing, as well as what else the filer is busy doing.
The f760 is rated (per SPEC, http://www.spec.org/osg/sfs97/results/) is abround 7500 NFSops with the read/write mix they put on it.
In one service (with almost equal reads and writes), we see somewhere around 75% cpu with 4k nfsops and 2M/sec in and 2M/sec out, on average. The peaks are much higher, and disk reads/writes are quite high. The cache age is low (3 min). This is on a loaded f760 with 1GB of cache, 3 raid groups of 14 drives (9GB) each.
On the other hand, in a mainly read environment I have seen filers push the 9k+ nfsops and pushing 10M/sec with highg cache age, while the cpu is still not higher than 80%.
It all depends on your mix and your configuration.
