A worker pool is 35 times slower than the main thread when each task needs 0.05 ms of CPU, and 3.5 times faster when each needs 222 ms. Twelve measured cases show where the line sits and why transfer beats structured clone.
Learn how to use Node.js worker threads for CPU-intensive tasks with TypeScript, including thread pools, SharedArrayBuffer communication, and when to use workers vs cluster. For backend engineers optimizing compute-heavy workloads.
