I’ve measured how many publishes per second can async_mqtt broker treated.
Environment
AWS EC2 c5.4xlarge, c5.12xlarge
-
Benchmark targets
-
mosquitto version:2.0.11
-
async_mqtt 1.0.6
Single broker, multiple clients. clients are genereted by https://github.com/redboltz/async_mqtt/tree/main/docker bench.sh
It publishes packets and receive it. Measure RTT(Round trip time). Each clinet 100 publish/second (pps). Increase the number of clients until RTT over 1second. For example, the number of client is 6,000, that means 600,000 (600K) pps. Publish payload is 1024 bytes.
