I've not heard of any such performance metrics, and I suspect it would
very much depend on how the filesystem was "aged". A filesystem that
has been in use for a few years and is at 80% capacity will behave
very different from a brand-new filesystem which was freshly formatted
and then filled with a few large files until said filesystem was 80%
full.
