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
});

首先在 macOS 上运行 node benchmark/http/simple.js，并检查 benchmark/http/simple.js，尤其是包含 duration: 5 的基准测试配置。调查报告的超时问题以及可能频繁绑定端口的行为；当基准测试在 macOS 上以原始时长运行且不发生超时时，工作即完成。
