| ## Notes |
| |
| Comparing the performance of `jwalk`, `ignore`, and `walkdir` and how well they |
| can use multiple threads. |
| |
| Options: |
| |
| - "unsorted" means entries are returned in `read_dir` order. |
| - "sorted" means entries are returned sorted by name. |
| - "metadata" means filesystem metadata is loaded for each entry. |
| - "first 100" means only first 100 entries are taken. |
