Benchmarks of various Entity Component Systems in Rust
Benchmarks of various Rust Entity Component Systems
Benchmarks
Benchmarks are run on Travis CI.
Benchmarks are located in benches/[bench_name]_[ecs_crate_name].rs.

Visualization of benchmarks, smaller is better.
pos_vel
- 1000 entities with
positionandvelocitycomponents - 9000 entities with
positioncomponents only - stub
rendersystem -
physicssystem:position += velocity
parallel
- 10000 entities with 3 simple components
R,W1andW2 -
w1system readsRand writes toW1 -
w2system readsRand writes toW2 - systems could be run in parallel
Notes
- the benchmarks explore a limited subset of ECS use-cases and do not necessarily reflect the peformance of large-scale applications
- froggy is technically not an ECS, but a Component Graph System (CGS)
