Special thanks to: Rsync over SSH - (40MB/s over 1GB NICs)
In this tutorial, we're going to setup the fastest way to do rsync over ssh that I have found. This will lose a lot of the benefits of SSH in that we'll be using no encryption after authentication.
If you'd like to keep encryption, you can skip the "NoneSwitch" and "NoneEnabled" parts of the HPN-SSH installation and remove -o NoneSwitch=yes
from the rsync commands. However, doing so will
obviously add some overhead.
