Yes, rsync protocol scales with the project size.

(assuming you are talking about git here)
Uhm no? git protocol scales with chageset size.  You don't retransfer
already transferred content.  So you will be tranferring only content
from the last git pull.

rsync checks the whole tree everytime.  The extra intermediate commits
that git sends out might be a lot smaller than cheking the whole tree
(and will be if you git pull frequently).  I find the "always" in the
first line highly surprising.  Did you make any tests?
