1 fanout exchange per room, and one server-named queue per chat
participant. Then extremely busy rooms will have less effect on other rooms.

Exchange-to-Exchange bindings offer another alternative but it's hard to
predict how it's going to perform and it's more complicated conceptually.

And, like with any performance considerations, I highly recommend
you to benchmark both approaches and see what the data says.
