Features and purpose

Performance analysis and optimization process. Use when code is slow, operations timeout, reviewing for efficiency, optimizing bottlenecks, or designing for high-load scenarios. Also use when users report slowness, someone says 'this should be faster', adding caching, or when code has nested loops. Essential for Big O analysis, N+1 query detection, database indexing, frontend Core Web Vitals, and profiling with language-specific tools.
