Node.js FAQ: Top Questions
44. How do you optimize Node.js event loop performance?
Event loop optimization in Node.js minimizes latency and maximizes throughput by reducing blocking tasks, managing callbacks, and tuning libuv.
-
Techniques:
Offload CPU-intensive tasks to workers, avoid sync I/O, limit
nextTickrecursion. -
Monitoring:
Use
perf_hooksto measure loop delay. -
Tuning:
Adjust thread pool size (
UV_THREADPOOL_SIZE). - Use Case: High-concurrency servers.
