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? -- Eray Aslan <eras@g.o>
