That should equal to something around 49 Mbps, correct? So what is the speed when dding the file locally on the server? (that is *not* the same as rsync) What if you then do the same thing on the server via a loopback mount on the server (i.e. mount localhost:/home /mnt)? Finally, if you do "nfsstat", what sort of values are you getting for "retrans"?
