prune empty dirs doesn't seem to be doing so.... && optimizations?

I'm using: (according to ps)
/usr/bin/rsync --archive --human-readable --acls --xattrs --hard-links
--no-inc-recursive --prune-empty-dirs --whole-file --one-file-system
But the difference FS systems get a full compliment of every dir in the
Perhaps it wasn't well tested when using a 3rd dir to compare against?
Also, anyway to optimize the same-system case (using shared memory).
Also an option to use inode numbers would greatly speed things -- since
are snapshots of each other both file systems will have the same inode
for files that equal.
As it stands, running the above rsync takes about 90 minutes/invokation.
The resulting 'differences' can be copied by "cp" in usually under 1 minute.
(a few Gig or less).
