There is a feature (Delegations) in NFSv4 that I think will help a lot
w.r.t. performance (it essentially gives a client exclusive rights to a
file). However, to the best of my knowledge, none of the extant clients
are using it effectively. (Solaris10 shipped with minimal delegation
support.)

I am just testing Delegation stuff, so I should know soon how much it
helps performance. But a production quality implementation of NFSv4
with delegations (client side) isn't out there at this point, from
what I know.
