Subject2.6.9-rc2-mm2 vs glxgears
DateThu, 23 Sep 2004 00:12:00 -0400
Greetings;

One of the things I noted about the last few kernels is that glxgears 
seems to get tangled up in a bowl of very stiff molasses, for 
instance from 2.6.9-rc1-mm5:

[root@coyote root]# glxgears
1622 frames in 5.0 seconds = 324.400 FPS
932 frames in 5.0 seconds = 186.400 FPS
800 frames in 5.0 seconds = 160.000 FPS
712 frames in 5.0 seconds = 142.400 FPS
637 frames in 5.0 seconds = 127.400 FPS
624 frames in 5.0 seconds = 124.800 FPS
564 frames in 5.0 seconds = 112.800 FPS
554 frames in 5.0 seconds = 110.800 FPS
553 frames in 5.0 seconds = 110.600 FPS
554 frames in 5.0 seconds = 110.800 FPS
554 frames in 5.0 seconds = 110.800 FPS
525 frames in 5.0 seconds = 105.000 FPS
499 frames in 5.0 seconds = 99.800 FPS
498 frames in 5.0 seconds = 99.600 FPS
499 frames in 5.0 seconds = 99.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
498 frames in 5.0 seconds = 99.600 FPS
499 frames in 5.0 seconds = 99.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
498 frames in 5.0 seconds = 99.600 FPS
498 frames in 5.0 seconds = 99.600 FPS
499 frames in 5.0 seconds = 99.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
498 frames in 5.0 seconds = 99.600 FPS
Broken pipe

But, imagine by surprise when I rebooted to rc2-mm2 and found this:
[root@coyote root]# glxgears
49 frames in 5.0 seconds =  9.800 FPS
46 frames in 5.0 seconds =  9.200 FPS
46 frames in 5.0 seconds =  9.200 FPS
31 frames in 5.0 seconds =  6.200 FPS <-I started kmail here
37 frames in 5.0 seconds =  7.400 FPS
49 frames in 5.0 seconds =  9.800 FPS
47 frames in 5.0 seconds =  9.400 FPS
49 frames in 5.0 seconds =  9.800 FPS
50 frames in 5.0 seconds = 10.000 FPS
50 frames in 5.0 seconds = 10.000 FPS
50 frames in 5.0 seconds = 10.000 FPS
50 frames in 5.0 seconds = 10.000 FPS
Broken pipe

Now, just for grins, I going to rebuild 2.6.9-rc1-mm5 without cachefs 
to see if that makes any difference.

Not enough to bother calling mother over:

[root@coyote root]# glxgears
1516 frames in 5.0 seconds = 303.200 FPS
983 frames in 5.0 seconds = 196.600 FPS
832 frames in 5.0 seconds = 166.400 FPS
703 frames in 5.0 seconds = 140.600 FPS
663 frames in 5.0 seconds = 132.600 FPS
623 frames in 5.0 seconds = 124.600 FPS
585 frames in 5.0 seconds = 117.000 FPS
553 frames in 5.0 seconds = 110.600 FPS
554 frames in 5.0 seconds = 110.800 FPS
554 frames in 5.0 seconds = 110.800 FPS
554 frames in 5.0 seconds = 110.800 FPS
554 frames in 5.0 seconds = 110.800 FPS
514 frames in 5.0 seconds = 102.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
499 frames in 5.0 seconds = 99.800 FPS
498 frames in 5.0 seconds = 99.600 FPS
499 frames in 5.0 seconds = 99.800 FPS
496 frames in 5.0 seconds = 99.200 FPS
Broken pipe

Its not using any cpu unless you count once or twice I saw it 
report .25%.

Definitely weirdsville incorporated though.
