Box Backup is not designed for speed, more for a steady trickle of
backups. The protocol is certainly not optimised for speed. For
example, lots of small files will be quite slow as it doesn't
pipeline the transfers. But when you're transferring big files, it
can go pretty quickly as it's just encrypting and sending.
Does this explain what you see?
