Hi,

I just enabled glvnd and noticed the performance is much lower.

glxgears: 14% perf drop
glvnd off: ~28000 FPS
glvnd on: ~24000 FPS

viewperf13 (some subtest): 11% perf drop
glvnd off: 201 FPS
glvnd on: 179 FPS

glvnd spends a lot of time in libGL.so and some in libGLdispatch.so.

The "off" results are with LD_LIBRARY_PATH redirected to libGL without
glvnd.

I'm curious if anybody knows how to persuade glvnd to be faster.

Thanks,
Marek
