📈 Expected behavior

I am publishing 50,000 messages (on a single topic) as quickly as possible. I have a subscription (setup on during connect) that should catch all messages.

The payload for each message is minimal (4 bytes).

I receive less than 11,000 message.

I expected to receive all QoS 1 messages that are published

If I do not try to publish messages concurrently all messages are (usually) received but it takes much longer.
