Notes:
- if a bench is written in the idiomatic way for an ECS, please let me know
- there will be more benches added soon
- the old parallel benches have been removed for now
- some older ECS that have not seen maintenance in over 3+ years are removed
Benchmarks are run on Travis CI.
Benchmarks are located in benches/[bench_name]_[ecs_crate_name].rs.

Visualization of benchmarks, smaller is better.
- 1000 entities with
positionandvelocitycomponents - 9000 entities with
positioncomponents only - stub
rendersystem physicssystem:position += velocity
- the benchmarks explore a limited subset of ECS use-cases and do not necessarily reflect the performance of large-scale applications
- froggy is technically not an ECS, but a Component Graph System (CGS)
