Subject: Re: [PLUG] ssh key based authentication
For those of you who use rsync over ssh for backups, I've found about
1.5x to 2x performance increases by going to the rsync protocol instead
of ssh, or using the rsync protocol tunneled through a VPN.
Turns out that SSH has substantial CPU overhead when using it to send
entire filesystems worth of data.
Cheers,
