           Summary: Okular takes too time to display the content of PDFs
                    while moving fast through many pages
           Product: okular
           Version: 0.8.2
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: maui.bugzilla at mailnull.com


Version:           0.8.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.28-11-generic

I have Okular installed and up to date from Kubuntu 9.04.

While viewing a PDF document, I do fast scroll down, but okular takes too time
(for me) to load each page.
If I go fast backwards through the already preloaded pages, they are displayed
correctly the way I expect for.

---> My computer is fast (3Gb RAM and Turion64x2 2Ghz) so I would like an
option to pre-load all PDF document at the beginning, so when I move through it
pages the first time, I can view its content instantaneously.

Note: I changed Preferences to Memory usage: aggressive, but this option
doesn't seems to take effect (after closing and re-opening to let the changes
to take effect)

Thanks!
