PRS-300 How long should a page turn take?

nimble · 03-26-2010, 01:58 AM

How long should it take to turn pages? It usually takes 2 or 3 seconds during normal reading, and usually longer with the first turn of a new book or when first fired up.

The memory is not particularly full, it has about 40 books loaded if that's relevant.

Thanks

That sounds a bit slow, mine sometimes takes a while doing things, but page turns are ok, sorry can,t be more help,

2-3 seconds sounds about normal for pdfs. That's what I have (text and graphics).
Book only will work a little faster (normally).
It's taking longer if the files are on external memory (SD-Card). I tried this once on my old 505. Moving the files from SD to internal memory sped up page turning time to approximately 50%.

I wouldn't worry about the 2-3 seconds unless you're in a rush reading your book ;-)

There are several reasons that page turn times can be slow. One is that the book is using special fonts. The second is that their are images on the pages. A third is segmentation. There are probably more.

Regarding segmentation, EPUB ebooks are split internally into segments. The ebook is really a ZIP archive, and segments are stored as individual files within the archive. Sometimes the segments are by chapter, sometimes by size, or sometimes as the publisher felt like.

My experience on my Sony 300 is that page turn time seems to depends on how far into the file segment I am. It starts at around 1 second. The further in, the longer it takes. If the segment is very long (some publishers don't segment at all), it can take several seconds. In one case I had it take up to 10.

You can test whether this is what you are seeing by noting whether the page turn time slows down as you progress through the book. When you cross a segment boundary, it will slow down once to open the segment (an extra second or two), then get faster, then start to slow down as you advance through the segment. This slowdown will be even more apparent when paging backwards.

My '10-second' book was in one segment. Around half way in, the page turn times because intolerable. Fortunately the book was DRM-free, so I could use Calibre to convert it from EPUB to EPUB. Calibre resegmented the book (and possibly did some other things) and the problem went away.

Hmm, interesting, I will keep an eye on where in the book I am. I had wondered if it was the type of book but so far it seems pretty similar regardless of whether calibre has converted it or not. I'm trying to avoid pdfs, and haven't been reading anything with pictures.

If you have pdf's and epub on the reader at same time it slows page turning down a lot, that is my experience.

Now that sounds interesting. I have a couple of epubs, but mostly I have pdfs. I'll probably try a epub vs. pdf only for the files I have on my reader the next time I connect to my pc.
