Ok, you are making me feel bad.

I've got an XP 1800+ on a MSI K7T266 board with a matrox G550 AGP
running in 1280x960 and X 4.3.0.1.  Noramlly run dual head xinerama but
this is running with one screen setup:

My fps is not quite so impressive as others have posted.  Before I loaded
my agpgart module I had:

$ glxgears

960 frames in 5.0 seconds = 192.000 FPS
960 frames in 5.0 seconds = 192.000 FPS
960 frames in 5.0 seconds = 192.000 FPS
916 frames in 5.0 seconds = 183.200 FPS

After insmod agpgart

1334 frames in 5.0 seconds = 266.800 FPS
1556 frames in 5.0 seconds = 311.200 FPS
1557 frames in 5.0 seconds = 311.400 FPS
1557 frames in 5.0 seconds = 311.400 FPS

Which is still less than exciting.  And that's the default window size
for glxgears.  Full screen (maximized) is real ugly:

164 frames in 5.0 seconds = 32.800 FPS
165 frames in 5.0 seconds = 33.000 FPS
164 frames in 5.0 seconds = 32.800 FPS

So is that just old, slow hardware[1], or should I be looking at other
possible problems?


Nothing jumps out in the logs:

[1] BTW -- I used to run swish-e indexing on this machine and it would
index 25,000 files in about a minute.  A few OS changes later, hard disk
upgrades, and another 1/4 of RAM and now it indexes those same files in
about 4 minutes.  So maybe something else is going on, but I don't know
where to start looking.  Any ideas?

Thanks,
