Great news! Node.js could greatly benefit from more reimplementations of its native modules. I had implemented the `fs.readdir` module in C and saw some good performance gains (it was a hackish experiment I did some time ago and can&#x27;t remember numbers).<p>The `http` module is said to be outperformed by `eshttp` [1] by a factor of 2 times, which is written in pure JavaScript.<p>There is also `node-lwan` [2], an experiment in using `lwan` [3] in place of the built in `http` module. Since its the most performant web server in JSON serialization, according to techempower.com benchmarks [4], performance gains are to be expected.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;iefserge&#x2F;eshttp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;iefserge&#x2F;eshttp</a>
