rsync - Jun 2009 - rsync --daemon. Can I open more than one instances?

Is there a way to speed up rsync by opening more than one daemon in
parallel. I use rsync --daemon to start rsync. I was wondering if
opening more than one instance is recommended or feasible? I know that
for services like nfs for example I have had opening many instances
improve performance.

I have 4 cores available so if there are any other parallization modes
I'd be glad to know since I need to backup ~800GB data every day.

daemon will create a process when a connection is established. So the
limit is hardware.

I think multi-client can improve performance, but limit is the same as
above.

What kind of performance you are concerning, network/cpu/ram/disk
IO ....?

It seems good :)

Rsync can backup only differs. I think you can use this feature.
