Slow page turns on smallest font (~3 sec)
I like to read my kindle on the smallest font. Page turns are extremely slow. ~3 seconds. Page turns aren't as slow on larger fonts.
This is on a book purchased from amazon. Is this normal? Are there any performance tweaks that can be made? |

There's much more text to process before displaying when using the smallest font. But 3 seconds is way too slow...

Just checked mine on a couple of books, and no problem in any of the sizes.
Interestingly enough, on my Sony 500, I purchased 3 or 4 books that had that probelm in the largest size. It started about a quarter way through the books, and got progressively worse as went ahead, up to as much as 7-8 seconds. Could not finish them. |

Does this happen to be a AZW1 e-book? These have embedded fonts, which might be why it is slow. In any case which book is it? If Amazon makes a sample available, we can all download and test it.

I just tested it on the User's Guide as well as a pure HTML file with only <p> tags (no fonts) converted with Mobi creator. Both around 2.9 seconds.

Size 1 ~2.9-3 sec Size 2 ~1.2 sec Size 3 ~1.2 sec Size 4 ~2.0-2.3 sec ??? Size 5 ~1.5 sec Size 6 ~1.5 sec |

Please post your sample file
Hello,
Would you please post your sample file in which you measured 3s for page turn? Thanks, Steven |

i see. I would like to understand how you are experiencing the delay. For example, are you timing it page to page? Or do you experience the delay as you finish reading one page and then turn the page. More over, do you only experience the delay for pages that have only text? only pictures? a mixed of picture and text?
For example, please note the user location ranges that you are experiencing the 3s delay from the Kindle User Guide. Thank you very much. |

This is odd - While testing just now, my unit locked up (Navigation bar was showing full bar, unresponsive). I hit home, after a few seconds it went back to the home screen. Now, page turns take about 1.1 seconds. It seems to be fixed now, but how do I repro it? And what happened? |

That's an interesting behavior... To paint a more complete picture, do you have a SD card install? Do you have a lot of books in the SD card? Have you recently move some new books to the Kindle via USB or download via Basic Web?

My guess is that some task was running in the background. The most likely candidate is the indexing of new content when it arrives (to speed up later searches). So if you recently added many files that might explain the slowdown.

Yeah, indexing could be responsible for this.
Someone told me something similar, that after adding the Feedbooks guide the Kindle was a bit unresponsive once. I guess that the indexing process can eat a lot of CPU cycles on the Kindle... |
