It depends on a large number of factors (such as hardware, usage
pattern, queue lengths, message size, persistence, etc.). You should
perform tests with realistic workloads to find the limit. RabbitMQ does
not impose any limit on number of queues, but you will probably need to
spread the load with clustering if you need more than tens or hundreds
of thousands of queues, depending on how busy they are.

RabbitMQ already performs internal storage optimisations for messages
that are routed to multiple queues.
