ECS c# Benchmark
February 21, 2025 · View on GitHub
This repo contains benchmarks of some c# ECS frameworks. Feel free to add your own or correct usage of existing ones! Please make your framework available as a nuget package to ease referencing and updating versions.
The benchmarks are not representative of usage in real conditions but results can still be interesting to look at.
All results are obtained from the same toaster, with the same load, so comparison is fairer.
Tested frameworks:
- Arch
- DefaultEcs
- Fennecs
- Flecs.Net
- Frent
- Friflo.Engine.ECS
- Leopotam.Ecs using what I believe is a nuget package not made by the actual author and compiled in debug...
- Leopotam.EcsLite using what I believe is a nuget package not made by the actual author and compiled in debug...
- MonoGame.Extended
- Morpeh
- Myriad.ECS
- HypEcs
- RelEcs
- Svelto.ECS
- TinyEcs
Removed frameworks:
- Entitas removed because it was taking forever to initialize in the later tests when moved to net8, you can check older benchmark results here
Tested versions may not be latest available, that's because I'm lazy and new versions may introduce breaking changes, so feel free to create pull requests to update libs you are knowledgeable about.

SystemWithOneComponent
Modify entities with one component. The padding aims to simulate real situation when processed entities and their components are not sequential.
Note: Padding tests were removed for libraries that use archetypes to save space as padding makes no difference in their results
