A quick data-point: the largest pubsub node *right now*, has a bit
over 73000 (73056 to be exact) subscribers, the top 3 are all above
72k. And this service is only for local users of the server.
[OT] And yes, even now, with only local users, we see a bit spike in
ejabberd when we have a new notification. This is a old version of
ejabberd and we are using a component connection, I'm sure that if we
move this to angie in 2.x we will improve a bit.
