This is a tool to benchmark RabbitMQ (AMQP 0-9-1) server performance.

It supports measuring the throughput and latency for publishing and consuming messages.

One of the most important metrics is the worst-case time, which quantifies the deterministic consistent performance that can be expected.

1. Start RabbitMQ server

   docker compose up -d
   

2. Run the benchmark for 30 seconds. One publisher and one consumer. The default test mode

   cargo run -r -- --server amqp://guest:guest@localhost:8491/ --duration 10 --interval 0.05 basic
   

3. This will report on the latency (round-trip time) and the throughput.
