https://bugzilla.samba.org/show_bug.cgi?id=5124 --- Comment #12 from Paulo Marques --- Using multiple connections also helps when you have LACP network links, which are relatively common in data center setups to have both redundancy and increased bandwidth. If you have two 1Gbps links

I made a bash script doing this in parallel, checks how many rsyncs are running and then starts another 'concurrent one'. My parallel sessions are against different servers. I doubt if it would make any sense doing multiple sessions between the same two hosts. My single rsync sessions was
