Eh, we served way bigger things, with millions of small files via NFS just fine. Out of non-SSD storage too. Their issue, as written in article, was SSDs failing.

It was migration from one clustered filesystem to another and the temporary step was just Apache equivalent of try_files and NFS mount aside the new FS while the migration was running in the background.

If anything filesystems are better with some nesting vs "one big dir"...
