Apparently yeah. Images are the only issue. This problem is with all pdf programs for Linux (and all depend on poppler). <div class="gmail_quote">On Sun, Dec 19, 2010 at 4:00 PM, JustFillBug <<a href="mailto:mozbugbox@yahoo.com.au">mozbugbox@yahoo.com.au</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">On 2010-12-18, dE . <<a href="mailto:de.techno@gmail.com">de.techno@gmail.com</a>> wrote: > > Foxit reader appears to be the fastest PDF reader in the industry, it seems > to be faster by many times than any other application available.

Apparently, decoding JPEG images inside PDF files are very slow, maybe it's just libjpeg was slow or the way poppler feeding libjpeg. But that's not the worst performance killer. What's kills the speed on evince is that evince try to preload 5-10 pages before it displays your current page. So every time you scroll back or forword a new page, you have to wait for it to finish the preloading of some other pages. Killed all the benefit of preloading. It should only preload pages on idle mode and when CPU load is low. If it detected the CPU load is up, it should stop the preload thing. No one cares how slow evince loading pages. _______________________________________________ poppler mailing list <a href="mailto:poppler@lists.freedesktop.org">poppler@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/poppler" target="_blank">http://lists.freedesktop.org/mailman/listinfo/poppler</a> </blockquote></div>
