# Objective - In preparation for an initial 2D/3D mesh batching/instancing PR, enhance `bevymark` to support some different test modes that enable comparison and optimisation of performance ## Solution - Use `argh` for command line interface options - Use seeded `StdRng` for reproducible random number generation - Add a mode for testing 2D meshes that includes an option to uniquely vary the data of each material by setting a random flat colour on the `ColorMaterial`. - Add a way of specifying the number of different textures to use for sprites or meshes. These are generated at the same resolution as the Bevy bird icon, but are just random flat colours for testing. - Add a benchmark mode that spawns all entities during setup, and animates the entities using a fixed delta time for reproducible animation. The initially-spawned entities are still spawned in waves and animated as they would have been had they spawned at intervals. --------- Co-authored-by: IceSentry <IceSentry@users.noreply.github.com> |

Stress tests
These examples are used to stress test Bevy's performance in various ways. These should be run with the "stress-test" profile to accurately represent performance in production, otherwise they will run in cargo's default "dev" profile which is very slow.
Example Command
cargo run --profile stress-test --example <EXAMPLE>
