# React Component Performance

## Overview

Identify render hotspots, isolate expensive updates, and apply targeted optimizations without changing UI behavior.

## When to Use

- When the user asks to profile or improve a slow React component.
- When you need to reduce re-renders, list lag, or expensive render work in React UI.

## Workflow

1. Reproduce or describe the slowdown.
