Try adding 'Option "MigrationHeuristic" "greedy' to 'Section "Device" of your xorg.conf, it may improve performance with EXA - however, some operations may still be slower than XAA. There are further optimizations in the works for EXA, but the real strength of the architecture will lie in its compositing abilities and speed in the near future.
