It outperforms Node.js/Express.js by 5x in response time and 10x in successful requests per second, maintaining 100% stability under load. The performance stems from JavaScriptCore's optimization, native HTTP server implementation, io_uring for async I/O, and zero transpilation overhead for TypeScript. ## Full article daily.dev links to this article rather than hosting it.
