RabbitMQ message delivery latency under 10ms requires tuning

Deploying a broker supporting high concurrency such as RabbitMQ or Redis should minimize message delivery latency to under 10ms per message. RabbitMQ frequently displays acknowledgment time spikes up to 40ms under heavy message volumes.

Monitor message delivery latency and tune broker configuration to maintain sub-10ms delivery times. For RabbitMQ, use direct exchanges and lazy queues to alleviate disk IO pressure during bursts. Benchmark message acknowledgment times under load.
