Do you have any Linux clients to test with?  That way you could determine 
whether the problem is on the server or the client side.  ISTR hearing bad 
things about Apple's NFS implementation (shocking, I know).  You also want 
to test with larger files (at least 2x RAM of the server or client, 
whichever is larger) to make sure you're not just seeing cache effects.
