Please describe the problem:
Evince becomes very slow and doesn't load this PDF correctly which has a ton of
graphics. If you go down a few pages after it finally does load a few pages,
you come to more loading screens. It just never finishes loading more than 2
or 3 pages at a time, and even that slowly.

Adobe Reader on Linux and WIndows reads it instantly though.

Steps to reproduce:
1. Open the attached
2. Try to click on random thumbnails
3. or just scroll around or on the bookmarks

Actual results:
very, very slow rendering

Expected results:
as fast as adobe

Does this happen every time?
yes

can you upload the pdf to some webspace and post the URL here or give the URL
of its original source?

pages 8 and 9 render really slow for me, the rest seems to be fine.

this looks like a bug with the PDF backend. Could you please follow these
instructions to help get this
bug fixed. Thank You. http://live.gnome.org/Evince/PopplerBugs#poppler

I'm having the same issue with another file.
It was created with Word on Mac OSX, pdf format 1.3.
I've tried to open the file with evince 0.5.2 on Ubuntu Dapper and rendering is painfully slow, but I found a workaround. I can print the file as .ps then use ps2pdf (ghostscript version 8.15.2) to get a pdf. The result is smooth rendering.
I'm using poppler 0.5.3 (and trying to compile the latest version :)

Cheers,
Luca

Still big, slow problem with Evince 0.8.1 using poppler 0.5.4 (cairo) in Ubuntu Feisty Fawn.

It's slow loading pages, maybe slightly improved since reported, but still not usable.  If I change pages, it takes around 5 seconds for each page to load, no matter if I visited it before, it says "loading".  Scrolling is not even an option since all I see is "loading" as well, I'd have to stop and wait 5 seconds for each page to load.

3:
your file wouldn't be similar to this one, would it?
this file renders slowly in evince but not in xpdf (though it looks somewhat better in evince when it finally does render)

i tried printing to ps and then running ps2pdf, but while the resulting pdf was much faster ("normal" speed), the image quality was degraded (not very noticeable at 100% zoom, but quite noticeable at 400% zoom)

All docs attached to this bug render fast for me. Feel free to reopen this bugs if the problem is still present for you with current poppler. 

Thanks.
