            Bug ID: 341161
           Summary: Utilize more than one CPU core
           Product: okular
           Version: 0.20.60
          Platform: Chakra
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org
          Reporter: richard.llom at gmail.com

Example PDF:
http://oneplus.net/downloads/presentations/oneplus-one-keynote.pdf
160 MB / 122 Slides

I wanted to view the above mentioned "heavy" presentation slide by slide. No
fast scrolling through, but just a quick glance at every slide.
However this was not possible, because the rendering wasn't fast enough and I
had to wait a little for each slide.

During the scrolling Okular used 100% CPU but only on one of my 4 CPU cores. So
I was wondering if it wasn't possible to use more than one core?

My CPU: AMD Phantom X4 955 @ 3.2 GHz
