Audit Performance

Performance analysis and recommendations.

When to Use

• Application feels slow
• Before optimization work
• After adding heavy components

Approach

Step 1: Project Invariants (Required)

Before auditing, check docs/knowledge-base/ for performance-specific constraints:

• Bundle size limits
• Load time requirements
• Any documented perf budgets
• Flag any violation of documented invariants as Critical priority.

Step 2: Focus Areas

• Bundle Size: Large dependencies, unused code
• Render Performance: Unnecessary re-renders, heavy computations
• Network: Large assets, unoptimized images
• Memory: Memory leaks, retained references

Step 3: Analysis

1. Check bundle analyzer output
2. Review React DevTools profiler
3. Check network waterfall
4. Audit image sizes

Common Issues

• Large dependencies that could be replaced
• Components re-rendering unnecessarily
• Missing useMemo/useCallback for expensive operations
• Unoptimized images
• Blocking resources

Output

Findings with specific recommendations and expected impact.
