Re: Disabling encryption for internal network

[Derek Atkins]

Are you sure that SSH encryption is actually slowing down the backup?  I
wouldn't think so, as most devices have AES in hardware and SSH is pretty
efficient.  Before you just bypass it, I would test to see if that's
actually the bottleneck.

You could just run raw rdiff vs rdiff-over-ssh to test.  I suspect the
local I/O is the bottleneck and not encryption or network speed.
