ECS c# Benchmark
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
- Entitas
- HypEcs
- 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
- RelEcs
- Svelto.ECS
