It's the number of files in the run that matters more than the amount of
date. Rsync loads the entire directory listing into RAM before starting
to copy so there is a certain amount of per-file overhead. It should
help if you could break the run up, perhaps doing a few directories
separately, then make another pass that excludes those directories.
