This is not correct.  The default "is unchanged" algorithm uses just the
size and the modify-time of the files, so it only needs to stat the
files.  If you specify -c, rsync checksums _all_ the files.  There are
also other options to modify how rsync decides a file is unchanged (e.g.
-I and --size-only), but these are specialty options that are not
typically used.
