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.

Comparison

Fastify processes 1.70x requests per second compared to Express, a 69.86% improvement.

Mode	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)
Fastify	9164 (+69.86 %)	3.5 ms (-41.30 %)	65.32 % (+1.42 %)	66.7 MB (-36.82 %)
Express	5395	5.9 ms	63.90 %	105.5 MB
