To keep in mind: I keep 14.774 books organized on 239 collections, storing them on a 32Gb Class 4 uSD SanDisk Card that I manage with Calibre

Even though the Collections' access time did improve to merely 20 seconds (compared to my previous 2 minutes or so on 3.12.1) almost every other function takes closer to 30 seconds or more: getting to the home screen, changing reading settings (while reading a book, mind you), opening the search option, getting to my library, changing configuration... all of it takes what it feels like forever, compared with the near instantaneous response on 3.12.1.

So: if you, like me, keep a large library on a uSD Card, with many a collection, and general interface time (not merely Collections access) matters to you, my advice is to pass this upgrade for Kobo Aura 2013.

On the other hand, if no matter the library size/storage/collections arrangement, you change or alternate books rarely and use other functions of the reader seldom, then by all means upgrade.

Anyway, that's my experience with this firmware.
Are you sure you installed 4.6.9995 and not 4.6.9960? Your description of the performance problems matches what I saw 4.6.9960. Kobo said that the problem was related to the sort order you used on the book list. But, it seemed to be triggered each time you did something that caused the book status to be saved. So, while reading, this could be closing the book to return to the library or home screen, sleep, opening the book details, search, opening the ToC and opening the reading settings. For some these it's not obvious why the status was being saved, but from them all you could either move to another book (search for a book, the related tab of the details) or make a change that mean the book had to be re-rendered. When the status is saved, there are at least four database updates made. And it would mean the "last read" date was changed triggering a resort of the book list if recent was being used. I assume someone messed up the sort or something.

For me 4.6.9995 is working well. The actions you mention are all under two seconds with just under 4000 books on my devices. I'll try dropping some more books on one of them to see if it gets worse quickly. Maybe there is a tipping point where the performance starts getting really bad.
