# Objective * Fixes #11932 (performance impact when stepping is disabled) ## Solution The `Option<FixedBitSet>` argument added to `ScheduleExecutor::run()` in #8453 caused a measurable performance impact even when stepping is disabled. This can be seen by the benchmark of running `Schedule:run()` on an empty schedule in a tight loop (https://github.com/bevyengine/bevy/issues/11932#issuecomment-1950970236). I was able to get the same performance results as on 0.12.1 by changing the argument `ScheduleExecutor::run()` from `Option<FixedBitSet>` to `Option<&FixedBitSet>`. The down-side of this change is that `Schedule::run()` now takes about 6% longer (3.7319 ms vs 3.9855ns) when stepping is enabled --- ## Changelog * Change `ScheduleExecutor::run()` `_skipped_systems` from `Option<FixedBitSet>` to `Option<&FixedBitSet>` * Added a few benchmarks to measure `Schedule::run()` performance with various executors |
