I have a fully updated fedora core system on my Laptop a Dell Inspiron 4150
p4 1.8 with 512 MB Ram and a Radeon Mobility 7500 running
kernel-2.6.0-0.test9.1.67
glxgears gives me the following frame rate
4169 frames in 5.0 seconds = 833.800 FPS
4266 frames in 5.0 seconds = 853.200 FPS
4269 frames in 5.0 seconds = 853.800 FPS
4271 frames in 5.0 seconds = 854.200 FPS
4272 frames in 5.0 seconds = 854.400 FPS
4272 frames in 5.0 seconds = 854.400 FPS
4274 frames in 5.0 seconds = 854.800 FPS
4271 frames in 5.0 seconds = 854.200 FPS
with RH9 i was able to get just over 500 FPS
Well done to whoever is responsible for the jump in performance
My best estimate, is that this performance increase is due to
Jakub's libGL optimizations and TLS support for Mesa libGL and
DRI modules. Also, libGL and all DRI modules are now compiled
with -march=i686 and TLS support, as well as the traditional i386
build. The proper one is automatically detected and used at
runtime.
There may be other performance gains here and there with other
things, but I believe Jakub's work gives the biggest boost.
I've CC'd Jakub with your comments, in case he isn't on the list.
Take care,
TTYL
