# Objective Based on and closes #18054, this PR builds on #18035 and #18147 to remove: - `Commands::insert_or_spawn_batch` - `Entities::alloc_at_without_replacement` - `Entities::alloc_at` - `entity::AllocAtWithoutReplacement` - `World::insert_or_spawn_batch` - `World::insert_or_spawn_batch_with_caller` ## Testing Just removing unused, deprecated code, so no new tests. Note that as of writing, #18035 is still under testing and review. ## Future Work Per [this](https://github.com/bevyengine/bevy/issues/18054#issuecomment-2689088899) comment on #18054, there may be additional performance improvements possible to the entity allocator now that `alloc_at` no longer is supported. At a glance, I don't see anything obvious to improve, but it may be worth further investigation in the future. --------- Co-authored-by: JaySpruce <jsprucebruce@gmail.com> |

Bevy Benchmarks
This is a crate with a collection of benchmarks for Bevy.
Running benchmarks
Benchmarks can be run through Cargo:
# Run all benchmarks. (This will take a while!)
cargo bench -p benches
# Just compile the benchmarks, do not run them.
cargo bench -p benches --no-run
# Run the benchmarks for a specific crate. (See `Cargo.toml` for a complete list of crates
# tracked.)
cargo bench -p benches --bench ecs
# Filter which benchmarks are run based on the name. This will only run benchmarks whose name
# contains "name_fragment".
cargo bench -p benches -- name_fragment
# List all available benchmarks.
cargo bench -p benches -- --list
# Save a baseline to be compared against later.
cargo bench -p benches -- --save-baseline before
# Compare the current benchmarks against a baseline to find performance gains and regressions.
cargo bench -p benches -- --baseline before
Criterion
Bevy's benchmarks use Criterion. If you want to learn more about using Criterion for comparing performance against a baseline or generating detailed reports, you can read the Criterion.rs documentation.
