Red Hat Bugzilla – Bug 84482
Interactive performance concerns
Last modified: 2007-04-18 12:51:20 EDT
Arjan asked me to file this for tracking.
On a 1GHZ Athlon with 512MB RAM and a Millenium ][ video card, the GNOME desktop
feels sluggish compared to the same experience with 8.0.
I bumped the X process using renice -10, does help much.
At 1280x1024 and 1024x768, the following is noticably sluggish:
1) open emacs with 'emacs -fn 10x20 <file>'
2) resize to height of screen
3) open a gnome-terminal and drag it (opaque drag in metacity) around in circles
across the emacs window.
4) you will see the gnome-terminal window trailing the mouse pointer, trying to
is interactivity with X reniced to -10 just as good as it was in 8.0?
we might as well consider using nice -10 for X, since the major complaint when
we did the nice -10 change was that 'gnome terminal is sluggish' - which turned
out to be a different bug (hopefully fixed in the next snapshot).
was there any other regression with the X server reniced to -10, other than the
i'm strongly in favor of reinstating the nice -10 priority of X.
we could do this in the kernel, but the preferred way would be to do it in the X
server. Any chance to have that done now?
What was the final resolution for this issue for new kernels?
That changing the X server priority is nothing more than a hack. Instead,
the kernel should work with interactive processes in a better manner. Our
current kernels IMHO do this MUCH better, and allegedly 2.6.0 test series
improves upon that, however I can't confirm that personally yet.
I think this can be closed safely now, but I'll leave that to a kernel
scheduler grand wizard. ;o)
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
