What does the "Average Latency per Protocol" graph/stat truly indicate in PA for NFS?
Is it latency for every NFS op that it's satisfying? Some of them? The highest latent operation?
I don't fully understand it because in PA, and running sysstat, there can be things going on that all seem to be happening very quickly, yet latency is huge. I mean in the tens of thousands of microseconds.
The particular case in question is attached as png (hopefully).
Thanks.

10 thousands of microseconds is not huge. It is just 10ms, which is not spectacular, but far below "huge".

If it were only 10k microseconds, maybe. But note the png I attached to the post, it shows 25k-35k microseconds. 25-35 milliseconds is pretty darned huge.
