rsync is never particularly fast as there is a lot of handshaking and file examination at each end prior to a transfer. I wouldn't be surprised at 50 Mbps.

scp should be a lot faster as there is no handshaking other than establishing the session; and the encryption/decryption process is not very compute intensive.

Having said that, scp and ssh are affected by the encryption algorithm. The fastest one at the moment is blowfish and it's possible to get up to 50 MB/s on a gig lan.
