With the help of the open-source MQTT performance test tool emqtt-bench, we test whether the client's Pub/Sub has a rate limit.

Originally published at https://www.emqx.com.

For deploying and running our cluster tests, we used AWS CDK, which allowed us to experiment with different instance types and numbers, and also trying out different development branches of EMQX. You can checkout our scripts in this Github repo. In our load generator nodes ("loadgens" for short), we used our emqtt-bench tool to generate the connection / publishing / subscribing traffic with various options. EMQX's Dashboard and Prometheus were used for monitoring the progress of the test and the instances' health.

You can use https://github.com/eclipse/paho.mqtt.java in Java.

We will use Eclipse Paho Java Client as the client, which is the most widely used MQTT client library in the Java language.

That’s an excellent question. What worries me is that there is no so much activity around the issues. For example just look at this https://github.com/eclipse/paho.mqtt.java/issues/896
