Slow Browsing Interface

Ah, I cleared the Media Library (while having the uniondb file on the flash drive instead of the shares) and it completely broke the ML–last content source removed and no longer able to select ML as a source.  Since I fairly often clear ML to get all file updates seen, having the uniondb on a flash drive is a no go.  In any case, once back to uniondb on (wired) shares, I see absolutely no speed difference scrolling through the ML.
