Sony PRS-505 slow whilst changing Chapters. XHTML too large?

Hi,

I have a problem of speed/flowing of pages/chapters. I am converting some novels into epub-format and am splitting the xhtml-files into chapters. Problem is that some books have large or no chapters.
I read that files have to be under 300KB. I have XHTML-files that are 150-250KB.

Some books that I have generated are really very slow on the Sony PRS-505. (20-30 secs when changing chapters). Could this be the problem? I am also using a pagemap.xml file for the pagenumbering (I am looking to put that info into the ncx at a later time).

Should I be looking at generating much smaller .XHTML files?

Cheers for any help

Pat

Slow movement between chapters is normal with Adobe's implementation of EPUB, and one of the reasons why I prefer LRF.

I have to stick with EPUB because it is the customer's specification.
By "Adobe's implementation" do you mean the pagemap.xml? I read a reply from kovidgoyal that style=pagebreak:always helps speeding the "TOC" display and wondered if periodically entering it in a few of the <p> tags after every few pages would speed the display. Would replacing the pagemap.xml with additional info in the ncx speed it up?
Cheers for any help or comments.
