I'm thinking of having around 50-100 client-side MessageBus subsriptions per client (they'll be different for each client, and the server's broadcast "subjects" will be dynamically assigned). Is this ok?

Or should I try to have fewer subscriptions even if the volume of messages will be the same (or even higher) if I do so?

What I'm really asking is..should I prefer more subscriptions or more messages per subscription? Is there any significant difference at all?
