FWIW, one of the big changes that went into SMB 3 for Win10 was adding the ability to do file transfers using more than one connection. CIFS (and windows) have traditionally been limited to 1 connection that everything was multiplexed over. However, CIFS in write/reads from a client to a linux server can easily get over 600MB/s writes, and ~275MB/s on reads. The reason it doesn't get more, is the cpu's start maxing out with processing interrupts and packets. I don't see rsync maxing out in cpu even doing a local->local copy, but I haven't done benchmarks on the newer versions of rsync, either. That said, I don't think the slow down is such that it would greatly benefit by multiple connections. My local disk can do read/writes to disk at around 1GB/s (for constant read/write). I'd be more convinced that parallel connections would benefit if there was any benchmarking done to find out where slowdowns are happening, but that's just my 2cents. :-) -- Please use reply-all for most replies to avoid omitting the mailing list.
