The big shelves have: 931, 66, 259, 211, 208 and 208 books (you can guess how that was sorted). Most of the rest are less than five books with a few between five and ten.
Opening the shelf list was about 40 seconds each time. I tried from the home screen and from the main library list. The speed was fairly consistent.
I took the card out and put it in the Glo. That took 11 minutes to process the books. Again connected to calibre and let it create the shelves. There were a few more shelves as there were already 200+ books on the Glo. But the sizes of the big shelves were the same. Actually, the numbers above came from the Glo. The big shelves should only have had books from the SD card, so they should be the same on both.
On the Glo, opening the shelf list list took 31 seconds. Where I started from or the sort order didn't matter. Again, the 31 seconds was very consistent.
A confession: This is actually with beta firmware on both devices. But, the figures for the Touch agree with what I saw with 2.6.1. And for anyone who wants to know, here's a hint about a change up there. And no, I'm not going to answer any questions.

I removed some books and timed shelf opening
This was on the Aura all books on SD card, no books on device, all epub.
I timed some twice once with counting and once with system clock and as you said the time was the same or close.
I am a bit baffled.
Reducing the number of collections seemed to make a reasonably consistent difference, but creating a collection of 231 books already on the device made it take almost 3 times longer. Then changing the shelf configuration to series from authors but still having the 231 book collection was fastest yet. I know that I have less shelves but if the 231 book collection added around 90 seconds why would it take much less time. Probably a logical reason but it eludes me.
I also cannot understand why the library list is so much faster. I have read claims that the books and/or database and/or covers must be processed, but are the covers/database/books not the same for the library list? I think of the library list as a large shelf, and the shelves as subsets of the library list.
Any light you can shed on this would ease my poor broken brain

PS still love your plugins.

Accidentally deleted reading and finished shelves. AGGGHHHH, must put on again
