Diagnoses latency issues, identifies bottlenecks, and resolves performance spikes in Node.js applications.
The Performance Debugger skill provides a structured methodology for identifying and fixing software slowness by measuring precisely and isolating bottlenecks. It guides developers through a systematic process: characterizing latency symptoms (P50 vs P99), breaking down request timelines across architectural layers, analyzing slow database queries with EXPLAIN plans, and monitoring Node.js event loop lag. This skill is essential for engineers needing to prove the root cause of service degradation before applying optimizations.
