I use the following options in my nfs mount (note some options may be
default and not strictly necessary but I have included them for
clarity)

auto,noexec,nosuid,nodev,intr,_netdev,async,timeo=25,hard

Specifically async is *much* faster than sync. I believe I set the
timeo=25 to avoid problems when my remote disk had spun down.
