gtkperf runs
Hello,
I'm running the xorg-edgers repository and noticed a very sluggish behaviour
under X11. The regression went away when running without KMS.
I did four gtkperf runs (see attachment) and the rendering time in KMS mode is
significantly higher than in the UMS case.
I'll also attach the Xorg-Logs from the UMS and KMS case.
Thanks
Matthias Bläsing
