# Objective It would be good to have benchmarks handy for function reflection as it continues to be worked on. ## Solution Add some basic benchmarks for function reflection. ## Testing To test locally, run the following in the `benches` directory: ``` cargo bench --bench reflect_function ``` ## Results Here are a couple of the results (M1 Max MacBook Pro): <img width="936" alt="Results of benching calling functions vs closures via reflection. Closures average about 40ns, while functions average about 55ns" src="https://github.com/user-attachments/assets/b9a6c585-5fbe-43db-9a7b-f57dbd3815e3"> <img width="936" alt="Results of benching converting functions vs closures into their dynamic representations. Closures average about 34ns, while functions average about 37ns" src="https://github.com/user-attachments/assets/4614560a-7192-4c1e-9ade-7bc5a4ca68e3"> Currently, it seems `DynamicClosure` is just a bit more performant. This is likely due to the fact that `DynamicFunction` stores its function object in an `Arc` instead of a `Box` so that it can be `Send + Sync` (and also `Clone`). We'll likely need to do the same for `DynamicClosure` so I suspect these results to change in the near future.
