Ark
Benchmarks

Benchmarks

This chapter gives an overview of the runtime cost of typical Ark operations. All time information is per entity. All components used in the benchmarks have two int64 fields. Batch operations are performed in batches of 1000 entities.

Benchmark code: benchmark/table in the GitHub repository.

Benchmarks are run automatically in the GitHub CI, and are updated on this page on every merge into the main branch. They always reflect the latest development state of Ark.

For comparative benchmarks of different Go ECS implementations, see the go-ecs-benchmarks repository.
