I see, well I guess the real question is whether it can be improved at the server/protocol level and my answer is I don’t know. There’s some handshaking that clearly has to occur between your instance and the other instance to load the initial community state and I don’t know where that process can be optimized. I think I’ve seen people mention tools that have been created to automatically subscribe a dummy account on your instance to all the communities on the largest instances to kind of bootstrap the process for other users, but I don’t have a link to such a tool handy.
