ssh is your problem; remember it takes CPU time to compress
everything, and over a 100MBit network, ssh takes far more CPU
time than rsync, which slows down the transfer considerably.

if you don't need ssh, take 10 minutes to set up rsyncd (rsync
--daemon mode), and copy it that way.  i've found that is far more
reliable than transferring over ssh, and it's _much_ faster, too.
