Version: 3.4.0 (using KDE 3.4.0, Gentoo) Compiler: gcc version 3.3.5 (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1) OS: Linux (i686) release 2.6.11-gentoo-r4 I have the kpdf Performance->Memory Usage set to "Aggressive" but still when switching to the next page, there is a delay as the page is rendered. Don't get me wrong here... kpdf in kde3.4 is like lightning. It just seems like the setting is not doing what it says it will do.
KPDF tries to balance the used memory against the free one. Aggressive tries to eat all your memory but preventing the tedious swapness. If it doesn't preload the next page it means that really free memory is very low.. better wait than turn on the HD drive. Let me know if it preloads next page when the system has plenty of really free memory.
I have Memory Usage set to "Agresive", but it doesn't preload next page. This is the out fo "free" command in console: #free total used free shared buffers cached Mem: 774916 571284 203632 0 13896 186652 -/+ buffers/cache: 370736 404180 Swap: 514040 100 513940 Is it not enough to preload next page?
I have 1 gigabyte of RAM and few running applications.. same observation.. not preloading the pages keeps me waiting.
I'm seeing the same problem with ~200MB free memory. In addition, pages previously rendered are immediately forgotten once out of view in "aggressive" mode.
I also experience this: The next page is not preloaded! Having 2GByte of RAM here (some hundred free). Please implement another strategy: "Always preload next page" which ALWAYS preloads the next (and maybe previous) page, but has variable strategy for other pages.

I have set the memory usage to "normal". Every time I go to the next page I get the described rendering delay. But going pages backward (to the one I had already viewed) I can go up to about eleven pages back wihout a rendering delay. So KPDF has obviously enoug RAM for about 12 pages. I would really like to see it that KPDF renders the next page in advanced and caches a page less of the previous visited ones. My KDE Version is 3.5.2
We did some work for KDE 3.5.6 that should improve the situation a bit. Feedback is appreciated and welcome, of course.
With KDE 3.5.5 the behavior is now quite well for me. While setting the memory usage to "normal" he is loading the next page in advanced, setting it to "low", kpdf does not. Thats the behavior I had hoped for :-)
Are you using non-continuous mode? Or continuous mode?
I am using non-continuous mode.
Anyone: if you are *NOT* using continuous mode: bug #147977 is for you.
It already worked, I remember it must have been 3.5.5. Back then, a 600 page document used to eat up all of my 1GB of RAM (no swap). Now I have 3GB and KDE 3.5.7/3.5.8 (gentoo), but the mem is not used in the slightest, even though I have set it to aggressive. I even tried it on a fresh and clean user account - in case I had some broken setting from long ago. But KPDF doesn't obey the setting, no matter what it's set to.
I think this should just be closed wontfix. Okular works great and I think kpdf is defunct.
