Well, I’ve don’t recall ever having to rsync more than 100G (although I am doing multiple rsyncs of about 86G as we speak), and I’ve never been able to do it with machines on their own, isolated switch (so my rsync’s are competing with everything else on the network), and it’s been a while since I’ve actually tried it multiple ways and measured it, but in my experience I’ve never see the network outperform the system bus.
