Package: okular
Version: 4:4.8.4-3+b1
Severity: normal
Tags: upstream
Dear Maintainer,
Searching (aka. 'Find') a larger pdf-document (1326 pages 11 MB) with a short
search string from beginning of the document to
the end used to take 22 seconds on my laptop with the squeezy version of okular
(okular 0.10... debian 4:4.4.5).
After a dist upgrade to debian wheezy (with okular 0.14.3 debian 4:4.8.4) i
noticed the same search slowed down to somewhat
over a minute. That's a slowdown by almost Faktor three.
Shouldn't new software generaly run faster?
It's anoying as I use searching larger pdfs rather frequently.
I noticed (using xosview) the old okular was running the search on a single cpu
core while the newer
one is using both cpu cores I have.
This means the total used cpu time increased by factor 6! I understand that
parallelizing an algorithm some tratdeoffs have
to be made, but factor 6 is absolutely unacceptable.
I understand that on an 8 core the new paralleliced search might require less
wallclock time,
but I *CANNOT* accept 'by an 8 core' as a bugfix.
The problem might very well reside in one of okulars library packages.
Please report this problem upstream.
Thanx
Thomas Zoschke
