LowLatencyOps

A field guide to running Aeron® in production — tuning, benchmarking, monitoring, and surviving the bad days.
Start with the tuning guide Aeron internals → The Aeron Files

The four pillars

Section titled “The four pillars”

Performance Tuning

The levers that move p50, p99, and throughput — BDP, term buffers, NUMA, kernel bypass, CPU isolation, JVM warmup, and the C vs. Java media driver.

Open the tuning guide →

Benchmarking

How to measure honestly: methodology, HdrHistogram, coordinated omission, and the published Transport / Cluster numbers at 100K → 5M msg/s.

Open benchmarking →

Monitoring

Reading the counters that matter — aeron-stat, aeron-stat-diag, cluster-diag, and what each signal tells you before it becomes an incident.

Open monitoring →

Operations & Resilience

Cluster Standby, disaster recovery, backup strategies, and a failure-mode runbook: node, network, disk, snapshot, and human-error scenarios.
