TL;DR

• Fastify is a fast and low overhead web framework for Node.js.
• This package shows how fast it is comparatively.
• For metrics (cold-start) see metrics.md

Requirements

To be included in this list, the framework should captivate users' interest. We have identified the following minimal requirements:

• Ensure active usage: a minimum of 500 downloads per week
• Maintain an active repository with at least one event (comment, issue, PR) in the last month
• The framework must use the Node.js HTTP module

Usage

Clone this repo. Then

node ./benchmark [arguments (optional)]

Arguments

• -h: Help on how to use the tool.
• compare: Get comparative data for your benchmarks.

You may also compare all test results, at once, in a single table; benchmark compare -t

You can also extend the comparison table with percentage values based on fastest result; benchmark compare -p

Benchmarks

• Machine: linux x64 | 4 vCPUs | 15.6GB Mem
• Node: v20.18.0
• Run: Mon Nov 25 2024 01:54:14 GMT+0000 (Coordinated Universal Time)
• Method: autocannon -c 100 -d 40 -p 10 localhost:3000 (two rounds; one to warm-up, one to measure)
