Linux Kernel Tuning for Performance
Kernel tuning aligns Linux scheduling, memory, and network behavior with your workload. Done carefully with measurement, it squeezes out latency and throughput; done blindly, it adds risk with no benefit.
Ana noktalar
- Baseline performance before changing anything and document the numbers.
- Tune one parameter at a time and re-measure to prove benefit.
- Adjust network buffers, backlog, and congestion control for your traffic shape.
- Set swappiness, huge pages, and memory limits based on workload needs.
- Pin and isolate CPUs for latency-sensitive processes where justified.
- Use sysctl settings managed by configuration management, not hand edits.
- Keep a rollback plan and test tuned kernels in staging first.
- Re-tune after major version upgrades and hardware changes.
Sık sorulan sorular
Is kernel tuning safe?
Yes when measured and reversible. Untested tweaks can hurt stability.
Which settings matter most?
Usually network buffers, CPU scheduling, and memory for your specific workload.
How do I know it worked?
Compare p95 latency and throughput before and after under identical load.
Should I tune defaults?
Rarely. Defaults are good for general use; tune only proven bottlenecks.
