Node.js Performance
Process Config
Tune cluster, heap, NODE_ENV, and libuv thread pool.
Detailed Description
Production Node runtime settings affect performance and stability. NODE_ENV, heap size, source maps, GC flags, and libuv thread pool size all change runtime behavior.
Tune these settings based on evidence. Increasing heap or thread pool size can help specific workloads, but it can also hide leaks or create more downstream pressure.
Mental Model
NODE_ENV=production heap limit threadpool cluster workers
When To Use
- ->Prepare production runtime defaults
- ->Use all CPU cores safely
- ->Tune crypto/fs-heavy services
Tools: PM2 cluster, Node cluster, UV_THREADPOOL_SIZE
