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. update benchmarks graph build benchmarks graph

pos_vel

  • 1000 entities with position and velocity components
  • 9000 entities with position components only
  • stub render system
  • physics system: position += velocity

parallel

  • 10000 entities with 3 simple components R, W1 and W2
  • w1 system reads R and writes to W1
  • w2 system reads R and writes to W2
  • 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)
You can’t perform that action at this time.
