Thanks for your testing and bug submission. Triaged to Confirmed. Tested with acroread 8 and it took 3 seconds. Since this is a 1950 book, the pages are scanned, so each page is actually a rasterized and compressed image. Not sure why kpdf would be slower, but it does make a good performance test case and I have added it to my collection of bad actors.
With KDE4 coming out, it would be interesting to test it against that build. Acroread is not open source, but it is free, and it seems to handle books well. ** Changed in: kdegraphics (Ubuntu) Status: New => Confirmed -- Extremely slow rendering of some PDF Files https://bugs.launchpad.net/bugs/178771 You received this bug notification because you are a member of Kubuntu Team, which is subscribed to kdegraphics in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
