Kafka, RabbitMQ and Pulsar measured side by side on ordering, replay and consumer scaling by driving the three client libraries directly, plus an operational-footprint measurement of each broker's own distribution. Nine tests, three brokers started without Docker, and every number in the documentation regenerated by scripts/run-all.sh.

Each broker started from its shipped distribution with default configuration and a
|
|
700 MB heap cap, on Temurin JDK 21. Times are one sample on a small box: treat them as
|
|
orders of magnitude, not as a benchmark.

NOTE: RabbitMQ ships no configuration file at all. rabbitmq.conf.example is
|
|
entirely commented out and the boot log records "Config file(s): (none)".
|
|
Everything in that file is documentation, not a default.
