You might find it noticably faster if you use rsync's -z option to
compress the data. It might also speed things up some if you go with
the blowfish ciper for ssh (ssh -c blowfish), as it's faster than
the 3des cipher, so your machines will spend less time encrypting/
decrypting and more time spitting data to the wire. Rsh is even
faster, but then you've gotta deal with the much lower level of
security provided by rsh, which might be OK on a machine that's only
accessible from trusted hosts on a trusted network...
