Summary: Large, persistent X virtual memory usage Product: okular Version: unspecified Platform: Compiled Sources OS/Version: Linux Status: NEW Severity: normal Priority: NOR Component: general AssignedTo: okular-devel@kde.org ReportedBy: jacob.benoi...@gmail.com Version: (using Devel) Compiler: gcc 4.4 OS: Linux Installed from: Compiled sources Hi, I am not even sure that the following is a bug, but I thought that I'd report it to you, so you decide. Summary: I ran 'top' and monitored the VIRT column for X. I understand that this is a completely broken way to measure memory usage. However, by just using Okular to view a PDF file at 400% zoom level, I was able to make that number go from 328M to 1500M. At 100% zoom, I still got 750M. This is on a machine with 1G RAM + 1.5G swap. Is is normal that this VIRT column for X would show such a large number as 1500M ? The system did feel a bit slower, but didn't crawl. Quitting Okular resulted in intense swapping for a few seconds. To reproduce: * launch 'top' in a terminal, note the VIRT value for X * wget http://www.jmilne.org/math/CourseNotes/LEC.pdf * okular LEC.pdf * Zoom to 400%. That's not necessary, but makes the "problem" worse. * Hit "next page" every time it has finished rendering * Iterate over a few dozen pages * Check back in "top" the VIRT column for X. I got it as high as 1500M * Quit okular. The system swaps for a few seconds. The X memory usage stays the same. * If you kill X and restart with XPDF instead, the X memory usage doesn't seem to significantly increase. Assuming that this is indeed not wanted behavior, here's some further info: * It's not specific to PDF, I got the same with DVI * At a Zoom level of 100%, I obtained a X (VIRT) memory usage of 750M. At 200% zoom, I got 1100M. * In 'xrestop', the okular pixmap memory usage may climb up to 100-200M sometimes, but not more, and eventually falls back to a low value. So this means that this isn't a pixmap leak, right? -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Okular-devel mailing list Okular-devel@kde.org https://mail.kde.org/mailman/listinfo/okular-devel
