HTTP Server Benchmark: Node.js vs Deno

This repository contains a benchmark comparison of HTTP servers implemented using Node.js and Deno. The goal is to evaluate the performance differences between these two environments in handling HTTP requests.

Introduction

Node.js and Deno are both JavaScript/TypeScript runtime environments. Node.js has been widely used for server-side development, while Deno is a newer runtime created by the original developer of Node.js, Ryan Dahl. This benchmark aims to provide insights into the performance of HTTP servers in these two environments.

NOTE: while using node cluster there will be some issue if you manage any kind of in-memory caching or global state that needs to be shared between these processes

Setup

Prerequisites

• Node.js (20.15.1)
• Deno (1.45.4)
• bombardier

Running the Benchmark

To benchmark the servers, we will use bombardier

1. Start the Node.js server:

node baseline.mjs

2. Start the Deno server:

deno run --allow-all baseline.mjs

3. Benchmark using bombardier:

Node.js

$ bombardier -n 10000 -c 30 http://localhost:8001/
Bombarding http://localhost:8001/ with 10000 request(s) using 30 connection(s)

Deno
