Overview

Real devices send messages at different rates and sometimes lose their connection. We built PSMark to test how messaging systems handle that traffic across several machines.

We used seven datasets to build 12 test workloads, then ran them on five MQTT brokers and one DDS implementation. We measured how long messages took to arrive, how many got through per second, and how many were lost.
