RabbitMQ 4.3 streams vs quorum queues, measured
A RabbitMQ quorum queue deletes each message once it is acknowledged and fsyncs before accepting it; a stream keeps it for rereading. On RabbitMQ 4.3.6, with 1 KB messages, the quorum queue moved 45,156 msg/s and the stream, over its own protocol, 281,330 msg/s, using 9 KB of memory per million messages against 20.5 MB.
