Update: Please see attached "all.tar.xz", which contains the following files: "x11perf -all" tests: 1) x11perf_8_fbdev.txt : Debian 8.11, mach64 removed 2) x11perf_8_mach64.txt : Debian 8.11, mach64 installed 3) x11perf_sid_fbdev.txt : Debian sid, mach64 removed 4) x11perf_sid_mach64.txt : Debian sid, mach64 installed 5) x11perfcomp.txt : comparison of the above four tests "/var/log/Xorg.0.log" files: 6) Xorg_8_fbdev.log : Xorg log file for test (1) 7) Xorg_8_mach64.log : Xorg log file for test (2) 8) Xorg_sid_fbdev.log : Xorg log file for test (3) 9) Xorg_sid_mach64.log : Xorg log file for test (4) "glxgears" (from mesa-utils) tests: 10) glxgears.txt Notes: a) "mach64" is short for "xserver-xorg-video-mach64". b) I was not able to install Michel's patch -- I wasn't sure what compile or other options to use. It looks like I could build a new kernel with that (patched) module; would that be the best way to include the patch? I see that a commit was made yesterday (Jul 10) related to the patch, so I can just wait and test it when it's available in Debian sid, or I can build a new kernel with the patch included. Please advise. c) The glxgears tests are included for reference. Those results give a better picture of the overall slowdown in X11 graphics from Debian 8.11 to Debian sid. The slowdown is most easily seen when running in multiuser mode with Xfce (see particularly the last two tests in the file), where the glxgears FPS is about 14.1 FPS in Debian 8.11 but only 4.7 FPS in Debian sid. So perhaps there are some interrelated issues with Xorg and Xfce and/or mesa-utils, especially since glxgears has intermittent segmentation and illegal instruction errors (only in sid). d) It takes approximately three seconds to open an xfce4-terminal in Debian 8.11, six seconds in Debian sid. e) Moving and resizing windows might be faster in all versions of Debian if the default setting would be to highlight only the window borders while moving or resizing, instead of including the window contents. This is probably an Xfce setting. -Stan Johnson user...@yahoo.com
