# Tuning and Troubleshooting

Guidance for tuning GridGain 9 performance, covering general considerations, JVM, operating system, persistence, SQL, and data streaming.

GridGain 9 exposes many settings that affect throughput, latency, and stability. This guide collects recommendations for tuning a GridGain cluster across several areas: general deployment practices, the JVM, the host operating system, persistence, SQL, and data streaming.

Start with [General Performance Tips](/docs/gridgain/gridgain-9/tuning-and-troubleshooting/performance-tuning/general-performance-tips.md) for a baseline checklist, then explore the topic-specific pages for the areas that matter most to your workload.
