Sure, they are usually mixed, but some tests emphasize (or stress)
file data IO vs. metadata more than others do.
And sometimes people ask for a metadata stress test, which would
focus on mv, ln, stat, etc., more than reading/writing file data.

That sounds like a filesystem IO test more than a metadata test,
though the problem could be in either area.

Hear?
