Source code examples for the Geek Time course 'Linux Performance Optimization in Practice' (《Linux 性能优化实战》). It provides reproducible C/Docker-based case studies covering CPU, memory, I/O, and network performance problems analyzed with Linux perf tooling.

Use cases

• learn linux performance tuning with hands-on examples
• reproduce high cpu usage scenarios and debug them with perf
• practice diagnosing memory leaks on linux
• analyze io latency and iowait problems
• generate flame graphs from perf data
• troubleshoot mysql and redis latency cases
• study network latency and dns performance issues

When to choose

• you are following the Geek Time Linux performance course and want the companion source code
• you want realistic, containerized scenarios to practice perf, flame graphs, and performance analysis
• you are learning to diagnose CPU, memory, I/O, and network bottlenecks on Linux

When to avoid

• you need a production performance monitoring or profiling tool rather than educational examples
• you are not on Linux or unwilling to use Docker and build tools
• you want a maintained library to integrate into your own software
