This thread seems to explain why I haven't been seeing the slow page turns that many are reporting. I use Sigil to reformat most of the sideloaded epubs I download. Part of my standard setup is splitting on chapter boundaries. Looking at the last set I modified (Thorne Smith from gutenberg.au, the chapter size shown by 7Zip vary from 11KB to 32KB uncompressed. Compressed size is about 35-40% of uncompressed size.
If I get the file in a non-epub format, I use Calibre to convert to epub and then clean up the file with Sigil. Takes a bit longer but makes my reading experience much better. Just one item with Sigil -- Save! Often!! The search and replace code tends to crash and dump all your work since the last save. Last edited by DNSB; 07-23-2012 at 12:25 AM.

My recommandation is NOT to change all your books because of a glitch in the firmware of the reader. If you can't stand it, use another firmware. That's why I did not use 1.9.17 although I could have fixed the top margin by reconverting all my books. |

The fact is that if the Zip algorithm compress the single file 1 by 1, so if you have only one big html file, this single file is "more compressible" that the respective part splitted in 25Kb chunk. Due to that, a "normal" epub generated by calibre will have 260Kb html chunk, and the same epub "optimized" will have about 10 time more smaller html chunk of 25Kb each, and this optimized epub will be bigger, because the zipping algorithm is less efficient. I also tried variation of zipping algorithm by manually decompressing and recompressing the epub using 7Zip. I've tried various compression setting (store/compress fastest/ fast/ normal /max / ultra - change word size from 8 to 128 bytes): the size of the compressed epub clearly change, but the page turn speed remain the same.

An "optimized" ePub will have more page break. The biggest book I have turned out to be about 80 "more" page in the "optimized" version (500 vs 580). This is my "worst case" scenario. For me this is a non-issue, I really doesn't care about page break... but for other people it can be different :-) Thanks for pointing this out. |

Hmm, I've never noticed any difference in page turn speed with 2.0. I'm either lucky or clueless (or both.)

About splitting the ebook: I usually split files/chapter. This way it's easy to have a link between the TOC and the actual files and it also gives an accurate page count. Anyway, what I'd really like to see is either epubs supported as kepubs or, lacking that, an epub to kepub conversion tool. |

I was perusing this this thread:
https://www.mobileread.com/forums/sho...d.php?t=186641 and noticed a comment about modifying css: adobe-text-layout: optimizeSpeed; Just curious if anyone has tried this and does it make a difference? |

I've just finished reading a sideloaded Baen epub (possibly converted by me from mobi, I forget) with no problems at all.
On the other hand, another file created by me from a Word document was pretty terrible, and seemed to get worse the further into the book you got. It did this before 2.0, but might now be worse. It's hard to say. This one was a single monolithic file. I have no idea how the Baen book was organised. Maybe I'll take a look this evening. (Incidentally, the second book also had problems paging backwards from the start of a chapter, which again was happening with the old firmware, too. The chapter breaks were added by me using an old version of Sigil - my netbook at home doesn't like the recent MacOS versions, but then it's not a real Mac.) |

ePub from Word can be nasty things. The only way to be sure they aren't nasty things is to go into the code and spend some time cleaning Words originating ePub.
