Nest: Express vs Fastify

Nest is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. It is built with TypeScript and combines elements of Object Oriented Programming, Functional Programming, and Functional Reactive Programming. Nest provides an architecture inspired by Angular for structuring larger Node.js applications.

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