It looks like ssh is the rate limiting step in your rsync.

What cipher are you using for ssh?

I use

rsync --rsh='/usr/bin/ssh -c arcfour128' ...

that helps quite a bit on my hardware, your hardware might do better
with another cipher.

You should check out https://bbs.archlinux.org/viewtopic.php?id=136713
