No, quite inefficient. We rebuild every file on the site regardless of whether something has changed, hence every time rsync runs it sees a modified file. What I had completely forgotten when I wrote that (and later noted when I remembered) is that rsync only transfers a diff of each files, so things aren't really that bad.
Of course, how it does that is a mystery to me - without fully comparing both versions, how can it create a diff? I guess that's what made it PhD material...
