           Summary: [Breezy] Slow random access and poor rendering
           Product: Ubuntu
           Version: unspecified
          Platform: i386
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: evince
        AssignedTo: seb128 at ubuntu.com
        ReportedBy: vincent.trouilliez at modulonet.fr

I have got lots of technical documents/datasheets in PDF format, and evince is
painfully slow to display the first page when I open a document, and trying to
access a random page (not contiguous to the page currently on screen ie) is very
slow too.
Also, the quality of the rendering is poor : I often can't even read the small
characters in diagrams.

I attached a (small...) data-sheet as an example. On this file, evince shows me
a blank page for what seems like ages, before displaying the page, yet as I
said, despite such a long wait, the text in the diagram is not even clean/sharp.

I tried with Acrobat Reader, and oh my god, I thought I was on another planet
altogether : it's simply lightening fast, absolutely blindingly quick, and the
quality of the rendering is very good too, diagrams are perfectly readable.
Accessing any page anywhere in the document is extremely fast too.
Okay, Acrobat is closed source, so maybe they use some magic that is patented
and/or too difficult to reverse engineer.

Soooo, I tried another OSS pdf reader...Kpdf, and was very pleased to see that
despite running in Gnome instead of KDE, hence not really 'at home' so to speak,
it was A LOT faster/livelier than evince, not as fast as Acrobat but not far
either, and the quality of the rendering of text in the diagrams was as good as
Acrobat. 

All tests were done with the apps' windows maximized, and the zoom factor set to
'fit width'.

So, I would sell my kingdom to see evince use whatever backend/algorythm Kpdf
uses...
