Created attachment 110276
Small file with several pages to flick through

Evince is extremely slow on some files, especially if it contains images or graphs.
I'm running Ubuntu 14.04 (libpoppler 0.24.5-2ubuntu, but it also affects Ubuntu 14.10 with libpoppler0.26.5). In earlier versions, the test pdf attached would render each page almost instantaneously, it now takes several seconds per page. Even Firefox (with the built-in PDF renderer, HTML5) can render this much more quickly.
In order to test this, it is not enough to look at a single page, but you need to quickly flick through several pages. Note that the file itself is pretty light.
I'm using Sandybridge integarted graphics, i5-2450M.

I don't see any page being slow when using glib/demo/poppler-glib-demo
nor qt4/tests/test-poppler-qt4

It would be useul if you could compile poppler from source use these
apps and tell us which page you find to be slow.

Title:
  evince is excruciatingly slow on some documents

Status in Poppler:
  Confirmed
Status in poppler package in Ubuntu:
  Confirmed

Bug description:
  Evince is excruciatingly slow when displaying the book available for download at http://www.safetty.net/publications/pttes
  Scrolling can take several seconds and will often just display empty pages. (And it is even worse with the 2009 version of the book you can still find on several places on the internet), while xpdf has no problems at all with instantly switching to the next page.
