As I understand it, zsync computes binary diffs client-side, rather than server-side as rsync does. Which I suspect would help with the first of the bottlenecks you mention above: CPU consumption on the server.
I have not used zsync myself, however, just looked it up when Sugarlabs folks mentioned it recently, so I might have misunderstood.
