[Bug 178771] Extremely slow rendering of some PDF Files

[Marvin Hankley]

Public bug reported:

Binary package hint: kpdf

There seems to be a problem with KPDF which causes it to render some PDF
files far more slowly than competing viewers, even ones which also use
poppler, causing PDF reading to be unbearably slow on my OK system. I'll
say that I've observed this problem with most PDFs. Here is one specific
PDF which exhibits the problem:

http://www.archive.org/details/unpopularessays027477mbp

For the record, my system is an Athlon XP 2600+ with 512 Mb RAM. I have
measured the average time taken to render page 100 of the above PDF in a
variety of viewers, using an average of 3 measurements.

XPDF : 2.5 seconds
KPDF : 16 seconds
Evince : 5 seconds
epdfviewer : 8 seconds

As you can see, KPDF is the worst performing by far. The large delay
when switching pages makes it impossible to use it on a daily basis.

Thanks a lot & happy holidays :-)
