      We have one queue. Imagine messages are produced at 2 msgs/s. There are three consumers and slow consumer limit is 1 msgs/s. What happens is that all three consumers get killed as slow, even though it is impossible for any of them to be fast, since messages are distributed equally between the consumers (round-robin).

      This has real consumer impact in a situation when producer rate is usually high (so it requires multiple consumers working in parallel), but may occasionally drop close to consumer-threshold. In this case, broker disconnects all consumers who then have to reconnect and message processing is delayed for the time of the reconnecting.
