I'm developing for crappy hardware and extremely slow internet connections, so as soon as it goes over 20, I start batch-processing. And I only stream in over the user's own inboxes, favorites, and some presents. It's full outbox (I add the outboxes of whoever is being responded to), but not full inbox, except on one component specifically for that.
Let me add some logging, to see how many relays the follows component has.
