Performance Tuning

Optimize Linux system performance through kernel parameter tuning, I/O scheduler selection, memory management, CPU governor configuration, and benchmarking. Covers methodology, real sysctl settings, and tool-based validation.

When to Use

• Server experiencing high latency, throughput bottlenecks, or resource exhaustion
• Preparing infrastructure for high-traffic events or load tests
• Tuning a database server, web server, or application host for production
• Diagnosing whether a bottleneck is CPU, memory, disk I/O, or network
• Establishing baseline performance metrics before and after changes
• Configuring kernel parameters for containers, VMs, or bare-metal hosts
