Xorg.0.log for accelmethod exa
System load slightly increases to almost 40% when EXA is enabled. The
video card is an ATI Radeon AIW X800.
As stressed in my original report, F8 is not affected even though it has the latest driver version 6.8.0, too. Setting component to xorg-x11-drv-ati thus appears questionable. Yes, you are right, I screwed up, but I am not sure that Xserver component is much better. Let's try to blame gnome-terminal (apparently the problem is somewhere there, because you cannot reproduce it with xterm). Alternative would be xfs (because bitmap fonts suck), but let's try gnome-terminal first. No change after downgrading to gnome-terminal-2.18.4-1.fc8. I have checked against Ubuntu 8.04, and for antialised fonts, system load varies between ~ 20% for accelmethod 'xaa' and ~ 40% for 'exa' which is enormous, too. Bitmap fonts were not available. Here, Xorg is at version 7.3 and GNOME at 2.22 whereas F8 sports Xorg 7.2. Not conclusive .. Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Issue still persists for current F9 including updates-testing. The xfs font server is clearly not involved since the Fedora default setup does not include it, and I have not added it afterwards. People using a dual core system will hardly even notice the issue but on a single core system, the impact on the system performance is significant. I still observe that using aliased fonts reduces the Xorg load from about 40% for bitmap fonts to about 20% which is still a lot. This issue is resolved or at least greatly reduced as of GNOME 2.24.x as included in recent F10 snapshots releases. This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
