Description
What is Performance Benchmarker?
A skill for systematic performance analysis. Covers Core Web Vitals measurement, bundle size auditing, runtime profiling, database query analysis, memory leak detection, and load testing. Produces benchmark reports with baseline comparisons and prioritized optimization recommendations.
Upgrade path
- 01Start with this package and validate the workflow.
- 02Add specialized skills or bundles once the core system is stable.
- 03Use the community to sharpen positioning, demos, and feedback loops.
# Performance Benchmarker Skill
## Measurement Protocol
Always measure before optimizing. Never guess.
### Core Web Vitals (Frontend)
- LCP (Largest Contentful Paint): target < 2.5s
- FID (First Input Delay): target < 100ms
- CLS (Cumulative Layout Shift): target < 0.1
- Tool: Lighthouse CI, WebPageTest, CrUX
### Bundle Analysis
- Run `npx webpack-bundle-analyzer` or equivalent
- Flag any single chunk > 100KB gzipped
- Check for duplicate dependencies across chunks
- Tree-shaking: verify no unused exports in bundle
### Runtime Profiling
- CPU: identify functions taking > 50ms on main thread
- Memory: heap snapshots before and after operations
- Network: waterfall analysis, identify blocking resources
### Database
- Log slow queries (> 100ms)
- Check for N+1 patterns in ORM usage
- Verify indexes exist on frequently filtered columns
- EXPLAIN ANALYZE on top 10 queries by frequency
## Report Format
| Metric | Current | Target | Status | Action |
|---------------|---------|---------|--------|---------------------|
| LCP | 3.2s | < 2.5s | FAIL | Lazy-load hero img |
| Bundle size | 340KB | < 200KB| FAIL | Code-split routes |
| DB p95 query | 230ms | < 100ms| FAIL | Add composite index |// Community acceleration
