# Objective Fixes #6689. ## Solution Add `single-threaded` as an optional non-default feature to `bevy_ecs` and `bevy_tasks` that: - disable the `ParallelExecutor` as a default runner - disables the multi-threaded `TaskPool` - internally replace `QueryParIter::for_each` calls with `Query::for_each`. Removed the `Mutex` and `Arc` usage in the single-threaded task pool. ![image](https://user-images.githubusercontent.com/3137680/202833253-dd2d520f-75e6-4c7b-be2d-5ce1523cbd38.png) ## Future Work/TODO Create type aliases for `Mutex`, `Arc` that change to single-threaaded equivalents where possible. --- ## Changelog Added: Optional default feature `multi-theaded` to that enables multithreaded parallelism in the engine. Disabling it disables all multithreading in exchange for higher single threaded performance. Does nothing on WASM targets. --------- Co-authored-by: Carter Anderson <mcanders1@gmail.com> |
