Performance Audit

Purpose

Identify performance bottlenecks across the full stack — rendering, network, bundle, database, and infrastructure. Produces a profiled baseline, a prioritized bottleneck inventory, and an optimization roadmap with estimated impact for each recommendation.

Scope Constraints

• Reads: Lighthouse reports, Core Web Vitals field data, bundle analyzer output, slow query logs, network waterfall traces, application source code.
• Cannot: Design caching hierarchies or TTL policies (use caching-strategy). Cannot model future traffic growth or define scaling triggers (use load-modeling). Cannot provision or deploy infrastructure changes.

Inputs

• Application URL or local dev environment access
• Current performance complaints or targets (e.g., "page loads slowly", "LCP > 4s")
• Tech stack details (framework, database, hosting, CDN)
• Traffic profile (approximate users, peak times, geographic distribution)
