I wonder where the perceived bottleneck is. I mean, you have two boxes
connected by ethernet (whatever speed), and you're running a sftp bulk

20% idle? Is the nework saturated or is there room for more throughput?
In other words, with a multiple-CPU box, how much would threads help?
Within the whole ssh section, where does the CPU spend its time? Is it
crypto or is it in shuffling network packets? Would offloading the
crypto to a separate process (and therefore processor) help?
This is silly. It seems you never moved a few Gbyte over an ssh Ethernet
connection and looked at the numbers.
Of course threads could speed things op thoroughly.
Intel doesn't put all those cores on a die for nothing...
