dfb may not be accelerating at all - or its so bad at it that just plain old
software in evas is better (if dfb isn't accelerating it is using its OWN
software rendering code of course - and this likely is slower than evas's
software).

from what i can see of the results you have - dfb doesn't seem to be
accelerating at all. just software. which makes dfb 100% useless. if it is
accelerating - either the way it's doing it is really bad, or the graphics
accelerator chip/core is just abysmal and useless.
