For what it's worth, I have my BackupPC server on a VM running on my office desktop PC.. The VM has 256 Mb RAM (it's Ubuntu Server). The backups are going to a 400Gb partition on a USB drive. I backed up my wife's 30Gb laptop (Thinkpad T23) with 512Mb RAM with Cygwin rsyncd in 325 minutes (50,000 files). After that, fulls (across wireless G) are taking around 160 minutes and incrementals are taking around 40...
This is all with no fiddling of the commands at all.... So your 1 day plus for 22Gb seems really, really high to me. Especially with such a beefy server.
