I realize this probably won't help if you're restoring single file database dumps, but for doing complete (rather than hand-picking single files) restores with a lot of files (about 70k in our case) using multiple tarsnap processes can speed things up dramatically. I wrote a little Ruby tool to do this for us years ago:
Again though, if that can be done with a tiny Ruby wrapper, it should be done in the default client. It's the only thing that makes doing complete restores for a catastrophic case of complete data loss almost tenable for us with Tarsnap.
