Hmm... this is kinda what I expected... nfsd is waiting on the local
filesystem....
Would it be nice if nfsd would know how to speak aio... but back to
reality.....
What happens if you double/triple (assuming you have enough memory) the
number nfsd
that are started? does it help or hurt? My guess is it probably will not
make a difference
but you never know....
