The basic problem is backuppc is using the file system as a database - specifically using the hard link capability to store multiple references to an object and the link count to manage garbage collection. Many (all?) filesystems seem to get slow when you get into the millios of files with thousands of links range. Changing the way is works (say to use a real database) looks like a very non trivial task. Adding disk spindles will help (particularly if you have multiple backups going at once) but in the end it's still not going to be blazingly fast.
