[hono-dev] Hono scalability study



We are studying Hono project and its usage in the IoT context. We would like to know the different scalability metrics of Hono project.

In this regard, are there any scalability analysis performed on Hono project? Please let us know.


Also, as the Command & Control API is still in development phase, Is it too early to perform the scalability analysis? Please comment.


As of now, We are planning to carry out the following tests

Latency Test: To capture the latency of Hono for different amounts of MQTT & HTTP clients and throughput (for different QoS levels).

Performance Test: To capture the resource usage of Hono where incoming message rates from HTTP & MQTT clients are high. This is to understand the behavior for telemetry use cases.

Throughput: Maximum number of messages per second that Hono can support (with a given CPU load of e.g. 70%). This can be derived from the performance test. Throughput could be measured for different machine sizes that Hono runs on (=> vertical scaling).


Are there any open source tools (something like malaria for MQTT) that I can leverage to obtain the scalability metrics? Please suggest.
