I had slow performance when one File Storage was inside other File 
Storage. In that case files from "_processed_" folder from the parent 
File Storage was treated as usual files and slowed down performance a lot.

Thats a common mistake. In most cases there should be only one File 
Storage and then usual Filemounts created. People tends to overuse File 
Storage as it was Filemount.

But maybe that not your case at all.
