Summary
A well-organized reference that pulls 70+ performance rules from Vercel's react-best-practices repo and sorts them by priority, from critical waterfall elimination down to advanced patterns. You get decision trees for things like when to Promise.all versus await sequentially, why barrel imports hurt bundle size, and how to authenticate Server Actions. Most useful when you're reviewing React or Next.js code and need quick answers on whether a pattern is worth fixing now or can wait. The priority index alone (waterfalls and bundle size are critical, re-render optimization is medium) saves you from bikeshedding micro-optimizations while missing the 200ms of sequential awaits sitting right there.
