Does a file's delta-compression efficiency in the pack-file directly

Yes. The on-the-wire format is a packfile. We create a new packfile on
the fly, so we may find new deltas (e.g., between objects that were
stored on disk in two different packs), but we will mostly be reusing
deltas from the existing packs.
So any time you improve the on-disk representation, you are also
improving the network bandwidth utilization.
The git-clone manpage says you can use the rsync protocol for the url.
If you use rsync:// as your url for your remote does that get you the
rsync delta-transfer algorithm efficiency for the network bandwidth
utilization part (as opposed to the on-disk representation part)? (I'm
new to rsync.)
