Node.js: The Road to Workers
summary
Node.js ships experimental multithreading via the worker_threads module that runs separate Node instances with separate event loops, supports SharedArrayBuffer and Atomics for shared memory and synchronization, and shows real gains — a reported 50% speedup on a 6‑core machine (5 ms → 2 ms) for a CPU task. Caveats: Windows startup/cleanup bugs, npm name conflicts, addon thread‑safety, expensive worker bootstraps, and terminate uses an uncatchable exception so API and behavior may change.
