Why does it focus on p95 metrics instead of averages?

Averages often mask tail latency problems; focusing on p95 ensures that the vast majority of users experience the app within defined performance SLAs.

Can it analyze Supabase database issues?

Yes, it benchmarks queries using the Supabase dashboard and pg_stat_statements, specifically identifying the performance impact of RLS policies and missing indexes.

Does it support automated performance checks?

The skill includes processes for integrating Lighthouse CI and bundle size budget checks into GitHub Actions workflows to catch regressions in PRs.

How does this skill help with React Native performance?

It provides specific methodologies for measuring cold start times, UI thread FPS, and memory leaks using tools like Flipper and the React Native Profiler.

분석 및 모니터링

Measures, analyzes, and validates performance improvements across mobile, web, and backend stacks using empirical data.

The Performance Benchmarker is a specialized engineering skill for Claude Code designed to replace guesswork with data-driven optimization. It provides comprehensive profiling for Expo (React Native) apps, Supabase databases, and Vercel-hosted web applications. By focusing on p95 metrics, statistical baselining, and tools like Lighthouse, Flipper, and Postgres EXPLAIN ANALYZE, it helps developers identify real bottlenecks and prove the effectiveness of their optimizations before and after implementation.
