The document I am reading now is rather simple, that might explain that I do not see any wait-dialogs. I also used a e-magazine, which gives both dialogs with normal and full-screen for most pages.
Unfortunately pre-caching is done by UDS of which no source code is published.

Hello Mackx,
You can check it with this test pdf file which I attached at my another thread in this forum some time ago.

And, I agree with you. It seems that only 'full screen' mode takes some rendering time every page turning on some exact PDF files. In my case, most of my PDF files don't show this problem but only 2 PDF files did.
But I couldn't express it well so I just mentioned it as 'pre-fetching'..
Then, if it is a problem or bug of the 'full screen' mode itself, it means that we can't solve it as a user, not a developer?
So far, the only solution for this problem which I've found is 'to turn off full screen mode'..

Hello Shaggy,
Yes, sometimes DR1000S shows phenomenal page turning speed on some text PDF files such as especially the DR1000S manual PDF inside. No loading time, nearly.
Maybe developers were satisfied with its PDF page turning speed as they test it with only that kind of PDF files.. Of course I don't know well..

I have a feeling that when the pages load too slow (perhaps somewhere between 10-15 seconds), the prefetching normally doesn't happen. I could be wrong though, I haven't tested this thoroughly.

Hello rvs,
Yeah, I also assume that djvu converting would be one of the best options. So I've tried it many times as what I posted in one of my old threads.
But some issues of this method blocked me..
1) a clash with CBZ
2) we can't merge the scribbles with Xournal
3) it would take much time to convert all of dozens of PDF files..
4) the margin data of a PDF file was lost when converting to a djvu file - this was the most serious problem in my case
However, if you don't have to care of those in your case, it can be a good solution.
