performance

# Performance This skill provides comprehensive performance capabilities including performance analysis, optimization, load testing, stress testing, capacity planning, and framework-specific performance patterns. ## When to Use This Skill - When identifying performance bottlenecks - When investigating memory leaks or high memory usage - When optimizing slow database queries - When analyzing frontend performance (Core Web Vitals, bundle size) - When setting up performance monitoring - When conducting performance audits before deployment - When creating load test scenarios - When analyzing performance under stress - When identifying system bottlenecks under load - When planning capacity - When setting up performance benchmarks - When optimizing React rendering performance - When reducing bundle size - When improving Core Web Vitals (LCP, FID, CLS) - When fixing memory leaks in React apps - When implementing advanced React patterns ## What This Skill Does 1. **Performance Profiling**: Analyzes CPU, memory, and network performance 2. **Bottleneck Identification**: Pinpoints specific performance issues 3. **Memory Analysis**: Detects memory leaks and high memory usage 4. **Database Optimization**: Identifies slow queries and optimization opportunities 5. **Frontend Analysis**: Analyzes bundle size, rendering performance, Core Web Vitals 6. **Load Testing**: Creates and executes load test scenarios 7. **Stress Testing**: Identifies breaking points and limits 8. **Capacity Plan...
