## 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": 2110, "days_push": 1399, "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
An open-source e-book (with accompanying code) on high-performance Go programming, covering profiling, data structures, concurrency, and compiler optimizations, plus common Go gotchas. It is written in Chinese and hosted as a series of articles on geektutu.com.

## Use cases
- learn go performance optimization
- understand go slice and range gotchas
- profile go programs with pprof
- learn goroutine concurrency control patterns
- prepare for go interview questions
- reduce go binary size and understand escape analysis

## When to choose
- you are an intermediate Go developer wanting systematic performance guidance
- you prefer tutorial-style explanations with runnable code examples
- you want a free, open-source reference on Go concurrency and profiling

## When to avoid
- you need official or exhaustively up-to-date Go documentation
- you cannot read Chinese and machine translation is unacceptable
- you are a complete beginner needing basic Go syntax first

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: benchmarking, developer-tools, concurrency
- domain: tutorials, performance, programming-languages, developer-tools
- platform: go, cross-platform
- tags: golang, ebook, performance-optimization, gotchas, pprof, goroutines, chinese-language
