# Threading

Configure threading, disruptors, and CPU affinity for optimal performance in your Rumi microservices.

## Overview

Rumi's threading model is built on the single writer principle with detached threads for infrastructure work. Configuration allows you to tune disruptor parameters, pin threads to specific CPU cores, and optimize for NUMA architectures.

Proper threading configuration is critical for achieving ultra-low latency and maximum throughput.
