## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2887, "days_push": 1335, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
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

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: monitoring, benchmarking, developer-tools
- domain: performance, operating-systems, tutorials, developer-tools
- platform: cli
- tags: linux-performance, perf, flame-graphs, case-studies, geektime-course, performance-tuning, linux, docker
