Are you sure the only change in your environment was BackupPC? I mean, did the file usage on any of the servers shift in some way so that more files are being backed up? Did you change transport mechanisms on any servers? File systems? I noticed my SMB backups began a lot faster when I upgraded from a 10/100 network port to a gigabit port on my backup machine, though rsync wasn't affected too much. Adding memory to it also helped I think (from 128mb up to 256mb, to reduce the amount of paging by measuring the high-water mark and surpassing it). I recently reduced it to take 2 backups at a time maximum, to help spread them out a little, since I have a blackout period during the work day, they tended to bunch up in the off-period. I also checked out hdparm to tune my disk a little... didn't help me, but that might help you. Depending on how loaded your server is, you may notice some backups that normally take a short while suddenly take longer, because it's paired with a backup that is hogging the system bus, disk i/o or cpu time. It would be nice to have more direct control over pairing, rather than having to set per-backup-set blackout times.
