Performance Optimization Skill

Comprehensive performance analysis and optimization techniques for identifying bottlenecks and improving application speed.

Description

This skill provides production-ready patterns, examples, and checklists for optimizing application performance across algorithms, databases, infrastructure, and code structure.

What's Included

Examples (examples/)

• Algorithm optimization - Improve time complexity (O(n²) → O(n))
• Database optimization - Eliminate N+1 queries, add indexes
• Bundle size reduction - Code splitting, tree shaking
• React performance - Memoization, virtual lists
• API response time - Caching strategies, async processing
• Memory optimization - Reduce allocations, fix leaks
