The optimization significantly improves the `process_example` method by avoiding unnecessary `Path` object creation for string inputs, achieving a **487% speedup**.
**Key optimization:** The original code always creates a `Path` object via `Path(value).name`, even for string inputs. The optimized version uses string operations for string paths and only creates `Path` objects when the input is already a `Path` instance.
**Specific changes:**
- Added explicit type checking with `isinstance(value, Path)` to handle `Path` objects directly
- For string paths, used `rsplit("/", 1)[-1]` to extract filenames, followed by `rsplit("\\", 1)[-1]` if backslashes are present
- This handles both Unix (`/`) and Windows (`\`) path separators without the overhead of `Path` instantiation
**Why it's faster:** `Path` object creation involves significant overhead including validation, normalization, and internal state setup. String operations like `rsplit()` are lightweight and operate directly on the underlying character data. The line profiler shows the original version spending 28,130 nanoseconds on a single `Path(value).name` call, while the optimized version completes the entire function in just 5,788 nanoseconds.
**Impact on workloads:** This optimization is particularly beneficial for components that frequently process file paths as strings (common in web applications), where the filename extraction happens repeatedly during UI rendering or example processing. The 5x performance improvement will be most noticeable in scenarios with many Model3D components or frequent re-renders.
