This line says
" You have 128 threads.
You have never used the last thread.
You have used between 1 and 12 threads (10%) for a total of 34.7 seconds.
You have used between 13 and 25 threads for a total of 2.23 seconds.
You have not noticably used more that 25 threads.
"
So if this load is typical, then you don't need more threads.

Everything else looks normal, but you haven't been running this server
for long. Maybe you need a longer period of data collection.

I don't use it. It should only improve performance if you loose
packets on your network. A well switched lan with uniform interface
speeds should not notice. If you have a saturated lan, or interfaces
of different speeds (e.g. Gigabit client, 100M server) then TCP could
help.

It would be great if an explanation of /proc/net/rpc/nfsd could go
into the HOWTO ... :)

up 133 days; doesn't seem like it's worth messing with it if the last
thread has only been used for 11 seconds. I might increase it for the next
reboot (if ever :-), but I don't really want to bother with restarting nfsd:

I'll look into it; there is already some discussion in the performance
section about some of the proc files, and the thread counts in
/proc/net/rpc/nfsd
