Hi all,
I'm seeing network speeds at about 35-45 Mbps when using BackupPC and rsync
over ssh.
Running iperf below I notice the network should theoretically be capable of a
bit more than that. I understand that ssh adds quite a bit of bottleneck.
[root@titan ~]# iperf -c cyndane

What about testing the speed over the ssh tunnel? That may tell you whether ssh
is slowing down your transfers or that it's due to rsync. If it is ssh, you
could trade encryption strength for speed.
Best,
Koen

You may wish to prevent ssh from using compression when using a fast
link, the overhead probably isn't worth it and may give you a reasonable
boost in throughput.
Like Koen said, you'll want to benchmark the different scenarios.

That sounds pretty good. But unless you have a lot of new files
created daily, the bottleneck is usually disk speed, especially

it is a frequent misconception that you *want* to see anything close to the
