Top 23 Performance Open-Source Projects

  • Gin

    Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.

    Project mention: Batteries Included Frameworks? Node/JS | | 2022-09-25

    Another good example would be Go. It's referred like "batteries included" language with excellent std lib. Yet it's not "like" Laravel. Even though some people tried to build framework like that, it failed to harness any kind of traction or interest there. And minimalistic, either no framework at all or something like gin (think express.js) is preferred.

  • leakcanary

    A memory leak detection library for Android.

    Project mention: Memory Leak with ViewPager2 and FragmentStateAdapter | | 2022-09-03

    First of all, grab the LeakCanary to check if you actually have a leak. Because just the memory increasing might be completely unrelated to your ViewPager.

  • Appwrite

  • fastify

    Project mention: How To Choose The Right Framework For Your Next Node.js App. | | 2022-09-23

    Fastify is a web framework highly focused on providing the best developer experience with the least overhead and a powerful plugin architecture. It is inspired by Hapi and Express and as far as we know, it is one of the fastest web frameworks in town. **source**

  • react-virtualized

    React components for efficiently rendering large lists and tabular data

    Project mention: How to render a component only when it's in the viewport? | | 2022-08-08

    Check out react-virtualized.

  • sharp

    High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, AVIF and TIFF images. Uses the libvips library.

    Project mention: 3 Methods of Automatic Image Generation: Image Generation API, Libraries, and Puppeteer Screenshots | | 2022-08-19

    The next option is to use an image generation library and implement the full solution yourself. Libraries like ImageMagick, Python Imaging Library (PIL), and Sharp in Node.js provide an API for image processing. Such libraries are typically used for resizing, cropping, changing image format, compressing images, etc.

  • Iris

    The fastest HTTP/2 Go Web Framework. Easy to learn. Fast development with Code you control. Unbeatable cost-performance ratio :leaves: :rocket: | 谢谢 |

    Project mention: Chi , gin , mux , fiber or standard library ? | | 2022-09-25

    Check Iris ( before you decide.

  • Fiber

    ⚡️ Express inspired web framework written in Go

    Project mention: Does Go have a widely used framework, or it's used without anything? | | 2022-09-24

    I recommend Fiber. Very flexible router.

    Project mention: Is there any way to return a store from createResource rather than a signal? | | 2022-09-14

    Solid 1.5 actually added this as an experimental feature. See the "More Powerful Resources" section in the release: Or the `createResource` API docs: You are looking for a `storage` config option.

  • ava

    Node.js test runner that lets you develop with confidence 🚀

    Project mention: Best test framework for Node in 2022? | | 2022-09-18

    We use node-tap at work which is similar to the new experimental nodejs test runner. There is also AVA which is also popular. I tend to lean more towards test runners that don’t pollute the globe namespace, that have a reduced api and rely less on mocking. If you write pure functions, then testing becomes much simpler and not much need for mocks.

  • DoraemonKit


  • k6

    A modern load testing tool, using Go and JavaScript -

    Project mention: Recommended tooling for load-testing an express REST API | | 2022-09-15

    Project mention: Native lazyload images vs other libraries | | 2021-12-07

    Since browsers support native lazy-loading, do we need libraries like this

  • inferno

    :fire: An extremely fast, React-like JavaScript library for building modern user interfaces

    Project mention: Current stats show that React is still by far the most popular and beloved front-end framework | | 2022-06-22

    Inferno (~6 years old) uses a VDOM, just like React, but it completely smokes React in benchmarks

  • C++ Format

    A modern formatting library

    Project mention: Ask HN: Best path/resource to learn modern C++ in 2022? | | 2022-09-21 and study the source code of some good-quality open source project, for example

  • Front-End-Performance-Checklist

  • go-perfbook

    Thoughts on Go performance optimization

    Project mention: Preferred resource for 'advanced' Go? | | 2022-08-11
  • partytown

    Relocate resource intensive third-party scripts off of the main thread and into a web worker. 🎉

    Project mention: What unpopular webdev opinions do you have? | | 2022-09-26

    You can offload this type of thing to a web worker using though, which will help lighthouse scores by getting it off the main thread

  • why-did-you-render

    why-did-you-render by Welldone Software monkey patches React to notify you about potentially avoidable re-renders. (Works with React Native as well.)

    Project mention: [Question] Is there a tool or method to measure/count the number times a component actually updates the DOM (commit), not just calls Render + Reconciliation ? Thank you. | | 2022-08-25

    I found this library to be most helpful with seeing why things are updating:

  • tvm

    Open deep learning compiler stack for cpu, gpu and specialized accelerators

    Project mention: Run Stable Diffusion on Your M1 Mac’s GPU | | 2022-09-01

    As mentioned in sibling comments, Torch is indeed the glue in this implementation. Other glues are TVM[0] and ONNX[1]

    These just cover the neural net though, and there is lots of surrounding code and pre-/post-processing that isn't covered by these systems.

    For models on Replicate, we use Docker, packaged with Cog for this stuff.[2] Unfortunately Docker doesn't run natively on Mac, so if we want to use the Mac's GPU, we can't use Docker.

    I wish there was a good container system for Mac. Even better if it were something that spanned both Mac and Linux. (Not as far-fetched as it seems... I used to work at Docker and spent a bit of time looking into this...)


  • BenchmarkDotNet

    Project mention: Sorting in C#: OrderBy.OrderBy or OrderBy.ThenBy? What's more effective and why? | | 2022-09-20
