seems to be a memory leak on poppler which is causing the issue, will attach a valgrind log shortly.

The document is really slow to render on poppler 0.12.4 , is easy to reproduce if you scroll trough the pages and wait for those to be rendered. Thanks!.

Ok, I tried with evince and didn't notice the slowness thanks to the evince page cache :-P The problem is not cairo backend specific, since most of the time is spent in GfxCalRGBColorSpace::getRGB(). With commit 65c14073a3b1035ca5fe3bd6667abd315272841e I've reduced the time to render page 4 from more than 5 seconds to around 3 seconds, so it's still a bit slow.

I've added a new optimization that axed the time from 1200ms to 600ms on my machine

Is this still an issue with Ubuntu 11.04 "Natty Narwhal"? What about with the Ubuntu 11.10 "Oneiric Ocelot" alpha 3 LiveCD updated to the latest versions of poppler (0.16.7-2ubuntu2) and evince (3.1.2-0ubuntu4)?
