Review Comment:
I executed the `ozone freon dtsg` command with `12` directory levels and a
span of `3` on my system, resulting in the creation of `265,720` directories -
each containing one zero-byte file (since the focus was on measuring the
traversal performance and not the data size).
The API call took around `33 seconds` to traverse the entire directory tree
structure.
