Is it possible to implement an option to run rsync in parallel?

Hello,

First of all thanks for your effort on maintaining rsync.

I am opening this discussion because I have noticed that when running rsync (I am on RHEL 7) they are spawn 3 processes and it usually copy at a speed around 50MB/s per process. This seems to have been observed also here:

I know there are "workarounds" using xargs or parallel commands to obtain more process running in parallel, but could it be took into consideration having an option, for example --parallel, to decide how many processes spawn?

Thanks a lot,
Edoardo

I think this needs some more information. What is the 50 MB limit from. Is it disk read/write, network, ssh compression or what.
