# Objective Remove `ArchetypeComponentId` and `archetype_component_access`. Following #16885, they are no longer used by the engine, so we can stop spending time calculating them or space storing them. ## Solution Remove `ArchetypeComponentId` and everything that touches it. The `System::update_archetype_component_access` method no longer needs to update `archetype_component_access`. We do still need to update query caches, but we no longer need to do so *before* running the system. We'd have to touch every caller anyway if we gave the method a better name, so just remove `System::update_archetype_component_access` and `SystemParam::new_archetype` entirely, and update the query cache in `Query::get_param`. The `Single` and `Populated` params also need their query caches updated in `SystemParam::validate_param`, so change `validate_param` to take `&mut Self::State` instead of `&Self::State`. |

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.
