Performance Audit

A practical performance review for web applications. Identifies the most impactful optimizations without premature micro-optimization.

When to Use

• App feels slow or sluggish
• Before launching to production
• After adding significant features
• When users complain about speed
• Planning optimization work

The 80/20 Rule

Most performance issues come from a few common causes:

1. Too much JavaScript (bundle size)
2. Too many re-renders (React)
3. Slow data fetching (waterfalls, no caching)
4. Large images (unoptimized assets)
