nfs client speed lower than expected.

What kind of speed should I be expecting over an NFS mount from
a linux box using a gig interface (igb)? I'm seeing linux clients
getting approx 2 or 3 times the throughput rsyncing files from a linux
nfs server that i get from a 8-stable FreeBSD client.
7.26MB/s - Freebsd client
21.10MB/s liunx client
I've tried a variety of files to try and take caching out of the
equation, I've tweaked a few sysctls after much googling
with no obvious improvement.
freebsd mount options
linux mount options
I have seen that using the linux server as an nfs client to write to the
NFS server on the freebsd box gives similar performance to a linux
client pulling from the linux server so I'm guessing its something to do
with the freebsd nfs client?
Any suggestions/clues welcome.
