Poppler has performance issues with the following PDF file: http://www.enrc.com/files/Annual_Report_2008.pdf On an AMD Athlon 64 X2 5200, the file takes 23 seconds to load in both Evince and Okular and maxes out the CPU. On a laptop with a slower Core 2 Duo chip, the same file loads in Adobe Reader in a little under a second.
I found a new PDF which exhibits the same problem but even worse: http://www.investis.com/bby/investors/reports/2008rep/anreview08/anreveview2008.pdf This PDF takes NINETY-EIGHT seconds from opening to display the first page!
I can confirm the slowlyness of the first pdf, it seems we are too slow doing PS operations to calculate color, but the second is acceptably fast here (3 seconds per page or so)

I received a poppler update overnight and now the second PDF takes 8 seconds to load, a significant improvement. But, the first PDF still loads very slowly.
I've made some optimizations to PS operations to calculate color and now it takes 6 seconds instead of 24 on my machine. I know Adobe is still faster but if that speedup is enough for you i'd like to close the bug.

Thanks for your work on this, Albert - that's quite a significant improvement! Six seconds sounds very reasonable, and certainly usable. Thanks a lot!
