I guess it's irrelevant, but when I tried using find on a pretty large folder tree on my Win2k system, using "find ." to get all the files was about twice as fast as using "find . -ctime 24". However, using "find . -printf "%p %c"" was about 20% slower than "find . -ctime 24", still faster than rsync which is about 60% slower than find with -ctime.

No. Rsync has to build a list of *every single file in the filesystem*, along with - at a minimum - last modified datestamp. Rsync needs to be able to propagate deletions if necessary, and to do that, you have to compare the entire list of all files (not specifically excluded) in the specified section on both volumes, not just the changed ones.
Also keep in mind that while if you're using the find / -ctime trick, YOU can assume that the other end is a mirror and you know exactly when the last time it was synchronized was, rsync knows no such thing. Rsync *produces* a mirror whether or not it started out with one.
