Some time take a look at lftp [1] and its mirror subsystem for this. It can break up a batch of files or even one large file into multiple SFTP streams. Another upside is that it can replicate most rsync behavior in a SFTP-Only Chroot account. Downside is that without a corresponding daemon like rsync on the other end directory enumeration is slow which isn't a problem if one does not have a complex directory structure. Play around with the built in rate limit options total and per thread to keep the network people happy. [1] - https://linux.die.net/man/1/lftp https://linux.die.net/man/1/lftp
