I have done a full benchmark of a POST REST API on my computer: Node.js vs Fastify vs Express.js vs Deno vs Bun vs GO. Node.js is used WITH and WITHOUT clustering on 6-core I7 processor

1. uWebSockets.js

   1 36 8,370 9.1 C++

   μWebSockets for Node.js back-ends :metal:

   

   If you'd like to test cluster mode, then use v19.3.0 as it described here https://github.com/uNetworking/uWebSockets.js/issues/593

   Simple, secure & standards compliant web server for the most demanding of applications

4. just

   3 25 3,677 2.5 JavaScript

   the only javascript runtime to hit no.1 on techempower :fire: (by just-js)

   

   https://github.com/just-js/just Is another for a V8 runtime, it really shows how well optimized it is. https://www.techempower.com/benchmarks/#section=data-r21

5. hyper-express

   4 38 1,897 8.3 JavaScript

   High performance Node.js webserver with a simple-to-use API powered by uWebsockets.js under the hood.

   

   Hey, I believe uWebsockets.js does support clustering. I'm the author of https://github.com/kartikk221/hyper-express which is written on top of uWebsockets.js and is pretty much the fastest webserver in Node land with an Express-like API and all of the common features such as middlewares, Router, async/sync, Websockets, Server Sent Events, File Uploading in a single package that is about same size as Express. The only catch is that you lose about 14% performance from the uWebsockets.js peak because of all the features but this is being improved and a well worth trade off for the familiar developer experience with still almost 2.5x performance of Fastify and other similar frameworks.
