I've seen several hundred Kbytes downstream FTP transfer before (from a remote internet site and I have no idea what the network characteristics were between my machine and that one).

I've Are you sure that is a little 'b'? If it is bytes, not bits, as most programs report rates then you had a 120 mb/s transfer rate.

NFS usually runs over UDP, but FYI TCP has "slow start" so that if there isn't a lot of bandwidth available it won't flood the network right away (it will pick up in speed as it realizes bandwidth is there however).
