Off the top of your head do you know of any file transfer tools that do utilize multiple streams?

Yes, I wrote down some that do and don't support it here:

I tend to use 'rclone', does SSH/more. The '--transfers' arg is useful for handling several files, lol. One, if I recall correctly, isn't parallelized.
