Yow!
cp_from_timer_nvlog = 19 cp_from_cp = 3312
Not too bad. Your NVRAM is full but not slowing you down all the time.
With so many ops I wonder if any of the counters "rolled over".
This is an F760 in a cluster. Our filers have 32MB NVRAM each. Will NetApp offer more than 32MB per filer?
Systat shows nearly constant write activity.
Netapp will no doubt offer more in the future, but they might not offer more NVRAM in older models, so 32MB may remain the max for your F760.
I think your filer is clearly overloaded with writes. Part of the problem is you set it up in a cluster, so you're really only getting half of the NVRAM. I think your best solution is to just move some of the traffic off to other filers, IF you actually find the filer to be slow. I would not add any additional traffic to it.
