TL;DR

  • Fastify is a fast and low overhead web framework for Node.js.
  • This package shows how fast it is compared to other JS frameworks: these benchmarks do not pretend to represent a real-world scenario, but they give a good indication of the framework overhead.
  • The benchmarks are run automatically on GitHub actions, which means they run on virtual hardware that can suffer from the "noisy neighbor" effect; this means that the results can vary.
  • 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.
  • bench: Benchmark one or more modules.
  • compare: Get comparative data for your benchmarks.

Create benchmark before comparing; benchmark bench

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
