I saw your post about FBReader 0.10.7 for DR800, but I am not sure about the slowness that you mentioned about 0.12.x. Do you mean it's slow when flipping page for 0.12.x or it's slow when starting FBReader? If you mean the later case, maybe it's because 0.12.x will do some sqlite database conversion (or initialization). It only happens once. If you mean 0.12.x is slow when flipping page, then I have no clue about how this could happen. I am using FBReader 0.12.6 on my iLiad, with some preloading mechanism. I can get page-flip in 2 secs (at most 3 secs). IIRC, I got similiar speed of page-flips on 0.10.x and 0.12.x without the preloading code.

Added:
I forgot to mention one thing about the possible cause to slowness. On iLiad, I have to modify registry.xml to make FBReader registered to certain IPC channel, or it will be extreme slow to start FBReader. It's also the case for other applications.

The slowness in v0.12.x is general, starting fbreader, loading a new book, flipping pages... Anyway v0.10.x is quite good, I'm converting .prc books to .epub format (I just discovered calibre includes a CLI command for that!) and I'll only use FBReader for .chm files.
My guess is that the few problems I've detected with 0.10.x are due to device running out of memory.

BTW, if not bothering, would you make some video of DR800 page-flips? I am curious about the speed of DR800, especially on FBReader. There is no such video available.

I've attached a video. The book is a 4 page .prc (Jan Neruda's Vampire if want to know

). As you can see, page flipping is over 1 sec (btw, similar than pdf or epub files with iRex document viewer). I observe identical performance with more complex and bigger documents.
Excuse the bad quality, I've recorded it with the mobile phone.
