It's my understanding the poor restore performance is a known issue with
tarsnap. I don't believe it's network or CPU related, but rather an
issue with the design at the server end. I'm fairly sure Colin plans to
fix it, but I've got no idea of when.

Hopefully he can give a more authoritative answer though.
