Performance Audit Framework

Initial Assessment Questions

1. What's slow? - Page load, API response, build time, runtime
2. How slow? - Quantify: 3s vs 30s matters
3. Baseline? - What's acceptable performance?
4. When? - Always slow, or under certain conditions?
5. Where? - Client, server, network, database?

Measurement First

NEVER optimize without measuring. Identify bottlenecks before fixing.
