This skill provides comprehensive performance profiling to measure, analyze, and optimize application performance across CPU, memory, I/O, and network dimensions. It helps developers identify bottlenecks, perform root cause analysis, and implement optimizations using tools like perf, Instruments, and clinic.js. Use it when you need systematic performance improvement through baseline measurement, detection, and optimization phases.

This skill provides comprehensive performance profiling to detect bottlenecks and optimize applications across CPU, memory, I/O, and network dimensions. It establishes baselines, identifies hot paths, and offers root cause analysis using platform-specific tools like perf and Instruments. Use it when you need to systematically measure and improve your application's performance.

This skill provides core R3F/Three.js performance optimization principles for developers when FPS drops below 60. It explains the critical 16ms budget for 60 FPS and offers actionable strategies like canvas configuration and draw call reduction. Use it to diagnose performance issues and implement essential rendering optimizations.

This skill provides Level of Detail (LOD) techniques for React Three Fiber (R3F) to optimize performance by reducing model complexity based on camera distance. It's used when complex 3D models cause FPS drops, especially in large scenes or on mobile devices. The implementation uses the `@react-three/drei` `Detailed` component to swap between high, medium, low, and billboard versions of a model at defined distance thresholds.
