I've been using NFSv4 extensively for several years and I've not had an issue
that you describe where everything is fine and then suddenly performance goes to hell in a
hand basket.
Yeah it's really annoying. I could accept it, if performance was
terrible all the time. I'd just figure I had some configuration setting
out of whack, but it's the fact it works great.. then wham. To be honest
it almost feels as if a cron job overnight it causing something to go
screwy. It'll run fine all day, the next day, back to shit. That's
without making any configuration changes.
It sounds as if you only have 2 systems to work with? No, tiebreaker
so to speak?
Actually, I have a couple of netbooks which hang off the wifi, although
the NFS exports are set to read only on those, it's probably worth
changing that and doing some further testing.
Have you considered running a VM on your client system to see if it
is affected in the same way?
I hadn't considered that. Good idea. When the client's having a crisis,
I can spin up the VM on the client and see if that's affected. I guess
it would it least tell me if it's a hardware/driver quirk or a software
issue.
