Dear All,
Could any one please provide me any information about MQTT Broker publish and subscribe handling like
1. How many requests it can handle like how many publish messages it can send in a second
2. How many subscribe requests it can handle per second give that i am using latest available processor. is MQTT broker has multi threading concept?

Right now i am working on finding the capability of MQTT Broker and MQTT client.

3. What happens when there are more requests than the MQTT broker can handle, wlll it crash or will it ignore all the messages when the Queue is full?
When happens when i keep all the nodes busy spamming.
Thanks in Advance!!
Regards,
Ravi

Sorry, i got the information by giving search the rate of MQTT broker is 30,000Msgs per second and it can slow down based on the server load.

Every MQTT broker is different and performance will vary based on many variables other than just the CPU of the server you run it on.

30,000 msg/sec for QoS 0 is not even close to the high end of the highest performing MQTT brokers. I am quite sure there are a few

that go higher than 1 Million or even 10 million msg/sec.
