- [ ] Overhead of conversions (i.e. `PyList` vs `Vec` etc.) - [ ] String `intern!` - [ ] `Vec ` becoming `list[int]` (and thus being very slow), usage of `Cow ` as an alternative - [ ] `#[pyo3(get)]` deep-cloning non-`Py` data - [ ] dictionary dispatch, i.e. look-up based on type object identity

調査方針: Examine the existing guide structure in the `guide/` directory of the PyO3 repository. Look at the 'Performance' section to understand the current content and formatting. Read the referenced items, such as the overhead of conversions between PyList and Vec, and the use of `Cow<[u8]>` for zero copy data. Consider consulting comments or asking maintainers for preferred depth and examples. Finally, write concise explanations with code snippets and performance benchmarks where applicable.
