Bug Report

Minimal reproducible repository

See https://github.com/nanoexpress/nanoexpress-vps-bench

Current Behavior

When comparing between native and Docker code execution difference is does 100% for me. After patching command it differs only ~35%. Looks like not a much difference, but it's a lot

Expected behavior/code

Maximum ~10% performance difference

Environment

  • Node/npm version: Node.js v10+
  • OS: Ubuntu, Debian, WSL2 Ubuntu/Debian
  • Addinational Info: Docker causes this

Possible Solution

Run code outside Docker, try use pm2 and cluster or Threaded mode

Additional context/Screenshots

See wrk results

As this is Docker issue, not nanoexpress, it's can be closed, but will be pinned
