Look at this!

3 frames in 6.1 seconds = 0.495 FPS
2 frames in 6.0 seconds = 0.333 FPS
2 frames in 6.0 seconds = 0.333 FPS

isn't it dreadful? Can you suggest me what I can do to diagnose this problem?

That's some pretty bad performance. Can you provide more info? Kernel? Distro? lsmod output? dmesg output? lspci output?

Here's mine:

6501 frames in 5.0 seconds = 1300.168 FPS
6534 frames in 5.0 seconds = 1306.775 FPS
6763 frames in 5.0 seconds = 1352.573 FPS

Yes. I am using a Debian Lenny+Sid/Experimental(just for a few KDE4 applications like Okular). My kernel is 2.6.28.1, built from debian unofficial kernel repository kernel-build site.

Thank you for your help!

Our systems and OS are pretty much identical. For starters, here's a copy of my xorg.conf that you might want to try.

Here you go:

Yes, I have some improvements, but I think it is still not good...

• 297 frames in 5.0 seconds = 59.317 FPS
  301 frames in 5.0 seconds = 60.064 FPS
  301 frames in 5.0 seconds = 59.991 FPS

Can you send the output of `glxinfo | head -5'.

It's synchronized with the vertical refresh rate. This is typical of the more recent Xorg Intel drivers. Try setting vblank_mode to 0 in your environment before running glxgears. While it won't improve your performance, glxgears should show a more impressive number as it is currently being limited intentionally. Also, glxgears isn't much of a benchmark. It might be helpful to know what version of the xf86-video-intel driver you are using. You might also want to take a look at the varius options in the driver's manual (AperTexSize, PageFlip, TripleBuffer, etc) that are related to 3D performance.

glxinfo | head -5

name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2

I think that is all right, Direct rendering is on.

BTW: can you please tell me how to save X startup data? I saw an [EE] there, but just a flash: too long output from X.

Code: Select all

$ env vblank_mode=0 glxgears

Yes, that make sense.

5153 frames in 5.0 seconds = 1030.576 FPS
5200 frames in 5.0 seconds = 1039.895 FPS
5227 frames in 5.0 seconds = 1045.315 FPS
5218 frames in 5.0 seconds = 1043.451 FPS

But I still bear slowness when use compiz or KDE4 Kwin, which I do not think should happen to my new T400.

Check out /var/log/Xorg.0.log to see what threw an error. btw. My glxgears results really don't change that much with vblank_mode=[01]. Here is my ~/.drirc for your interest.

<driconf>
<device screen="0" driver="i965">
<application name="Default">
<option name="force_s3tc_enable" value="false" />
<option name="fthrottle_mode" value="2" />
<option name="vblank_mode" value="1" />
<option name="allow_large_textures" value="2" />
</application>
</device>
</driconf>

Thanks all! I have done that. My problem is, I am using i965 driver and libdri in debian experimental, but using xserver-xorg in debian lenny. Thus, lenny Xorg can't start on experimental libdri due to the incompatible. Now I am using compiz+KDE3.5, and it is really smoothly!

I don't know much about what's in the debian repos, but you could look into building the whole X stack from the git repos.
