Additional information

I found that it works when I change duration from 5 to 10. It could be some problem with frequently port binding.

const bench = common.createBenchmark(main, {
  // Unicode confuses ab on os x.
  type: ['bytes', 'buffer'],
  len: [4, 1024, 102400],
  chunks: [1, 4],
  c: [50, 500],
  chunkedEnc: [1, 0],
  duration: 5 // replace with 10, it works
});

まず macOS で node benchmark/http/simple.js を実行し、benchmark/http/simple.js を調査します。特に duration: 5 を指定したベンチマーク設定を確認してください。報告されているタイムアウトと、ポートバインドが頻繁に発生する可能性のある挙動を調査します。macOS でベンチマークが元の実行時間でタイムアウトせずに実行されれば、作業は完了です。
