FWIW, I've found that different builds of rsync/d and Cygwin differ
*dramatically* in their performance on Windows.

By dramatically, I mean after switching out my rsync binaries, a
representative full backup went from 220 minutes to 95, and a
representative incremental backup went from 200 minutes to 7.  Yes, seven
minutes, and the only thing that changed was the rsync binary on the
Windows system.
