This is not much load at all, an iPhone running RabbitMQ could process many millions of messages per day. Even 1M messages per day is only 11 messages per second average. i.e. not taxing at all.
I find it amusing that we happily play these AAA gaming experiences that are totally fantastical in their ability to deal with millions of things per frame and then turn around and pretend like hundreds of thousands of things per day is some kind of virtue.
