I thought this might be of interest even to people other than Sony PRS-505 owners and individuals who want Wikipedia as an eBook... so I'm starting this thread here, with much the same information I posted in an earlier thread.

I have just successfully loaded a PDF with the following attributes:

- 53,432 pages
- 133.2 MB
- at least 15,000 items in external table of contents (2540 first level items, and each of those has 4 - 15+ subitems)
- all pages basically full of text (content is the complete Summa Theologica repeated 5 times over)

When loading it from my old-ish SD card, I've observed the following:

- There is a one-time 7-8 minute loading time.
- Page turning is slower than usual... about 3 seconds, but regardless whether one is going to the next page, or 30,000 pages further in the text.

When loading it from main memory:

- There is a one-time 4 minute loading time.
- Page turning seems consistently about 3 seconds still.

Warning: Don't ever try to actually use an *external* table of contents that has over a hundred thousand entries. My PRS-505 spent several "hours" formatting before I was somehow able to get it to reset. (Initially it was even ignoring my poking the reset button in the back... though otherwise it seemed like it was actually working/processing, not frozen.

---------------

I should mention that, in contrast, a 10,000 page PDF has less than 1 minute one-time loading time and pretty snappy page-turning.

Also, the reason I went for a 50,000 page or so PDF is because LaTeX memory limits (with all settings maxed out) still seem to kick in a few hundred pages before 60,000--albeit this isn't a page limit, but a text (i.e.: string) limit.

If anyone manages to generate a similarly content-heavy PDF with over 100,000 pages, please post what you did.
