Benchmarking programming languages and web frameworks

Bun.serve (JavaScript)

Bun.serve is a part of the Bun toolchain, which is a fast all-in-one JavaScript runtime, package manager, and bundler. Bun.serve is specifically focused on serving HTTP requests and is designed to offer high performance and simplicity in developing modern web applications.

This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.

MedianP99

Framework	Requests per second Indicates how many requests per second the framework can handle. (higher is better)	Latency Indicates how long it takes to process a request. (lower is better)	Stability Indicates how stable the framework is under load: median / P99 latency (higher is better)	Memory Indicates how much memory (RAM) the framework uses. (lower is better)

JavaScript is a high-level, dynamic programming language that conforms to the ECMAScript specification. Originally developed by Netscape to add interactive elements to websites, JavaScript has become a core technology of the World Wide Web, alongside HTML and CSS, and is supported by all major browsers without the need for plugins. Node.js, a JavaScript runtime, allows for JavaScript to be used on the server-side, enabling the development of fast, scalable network applications. This versatility makes JavaScript unique in its ability to handle both client-side and server-side programming.
