Welcome to Mordor! Hunting Performance Issues in Node js
summary
Covers concrete debugging steps: use process.memoryUsage, V8 heap snapshots and CPU profiles via the V8 API, serialize snapshots and inspect them in Chrome DevTools to find leaking objects and call stacks. Demonstrates automated delta-based snapshotting (take snapshots when memory crosses a threshold), shows a real Express development vs production case (about 75% slower in dev), and explains marketplace incidents (Netflix, Walmart) and when core bugs require upstream fixes.
