React performance is less about one trick and more about a repeatable checklist: measure, isolate, fix, and prevent.
1) Start with profiling (not guessing)
- Use React DevTools Profiler.
- Find components re-rendering too often.
- Confirm renders cause slow frames.
2) Memoization: use it surgically

Avoid re-creating props
const value = useMemo(() => computeValue(data), [data]); const onClick = useCallback(() => doThing(id), [id]);System Architecture Specifications & Quality Checklist
