‘Reasonable’ here is a bit subjective I think. At least I don’t see how replication can be implemented without some performance cost. Would love it if it could, but it’s a no-free-lunch world and these guys seem to be striking a fair balance in delivering replication that is ‘reasonably’ performant.
