Top 23 C# Performance Projects

  • BenchmarkDotNet

    Powerful .NET library for benchmarking

    Project mention: Which would be faster to update all values? 3 layer list, 2 layer array or 1 layer array? | reddit.com/r/csharp | 2023-01-28

    You can use BenchmarkDotNet to quickly write your own reliable benchmarks and run them on different target runtimes.

  • Entitas

    Entitas is a super fast Entity Component System (ECS) Framework specifically made for C# and Unity

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • Project mention: Edsger Dijkstra - math and memes | reddit.com/r/ProgrammerHumor | 2022-12-16

    In Unity, the implementation was done by moving functions from the Entity to the Archetype, which then can be accessed via interfaces. Those interfaces can be inherited in classes. I have "running, waiting, scanning" behaviour classes that get applied to those Archetypes, so OOP is still there but different.

  • perfview

    PerfView is a CPU and memory performance-analysis tool

    Project mention: Using VS: Code as IDE for C# | reddit.com/r/csharp | 2022-09-28

    I've found dotnet-trace + speedscope to be ok if you just want a hint on where time is going. There's also perfview but it's Windows only.

  • optick

    C++ Profiler For Games

    Project mention: Tracy: A hybrid frame and sampling profiler for games and other applications | news.ycombinator.com | 2023-01-28

    I have used Tracy to improve the performance of a latency sensitive application. The main advantage of this tool, in comparison to something like the Visual Studio profiler, is the fact that it can highlight the inter thread dependencies and synchronization between the threads. The other main feature, in my opinion, is the statistical tab that is associated to the recorded events: it can show the statistical distribution of the duration of all the invocations of functions and it allows to identify patterns in the performance of the application. Furthermore, a table can be used to sort the invocations of the functions and quickly jump to the point in time when the sample was recorded.

    Other notable tools that implement a functionality similar to what is provided by Tracy are Optick https://github.com/bombomby/optick and Intel VTune (sadly specific to only Intel processors) in the Threading analysis.

  • App.Metrics

    App Metrics is an open-source and cross-platform .NET library used to record and report metrics within an application.

  • ComputeSharp

    A .NET library to run C# code in parallel on the GPU through DX12, D2D1, and dynamically generated HLSL compute shaders, with the goal of making GPU computing easy to use for all .NET developers! 🚀

    Project mention: What library to code a Screensaver? | reddit.com/r/csharp | 2023-01-07

    Create a UWP or WinUI 3 applicaation and use the AnimatedComputeShaderPanel from ComputeSharp. The library lets you write shaders (ie. code to run on the GPU) entirely in C#, and handles all the logic to setup a DX12 animated swapchain, similar to Win2D. If you look at the repo you can also see a whole bunch of examples, which you can also try out for yourself. There's also several wiki pages with lots of info.
