Does A Greedy Intel Driver Improve Performance?

EXA with the default options in the xf86-video-intel 2.6.3 driver provided the best performance for the GtkComboBoxEntry widget. Using the EXA greedy mode was slower by about 30% while the UXA and xf86-video-intel 2.4 EXA modes ran at roughly the same speed as the xf86-video-intel 2.6 EXA combination.

UXA was slower than the rest when it came to the GtkRadioButton widget. Using greedy migration heuristics led to slightly better performance, but it still was behind in performance compared to the xf86-video-intel 2.4 driver series.

Everything besides using the xf86-video-intel 2.6.3 driver with the default EXA options led to better performance with the GtkTextView scrolling operation.

UXA regressed horribly, again, when it came to the GtkDrawingArea Circles. The default configuration exhibited the best performance while EXA Greedy caused a slight slowdown. Fortunately, the xf86-video-intel 2.6 driver was faster than the 2.4 series.
