It'll vary enormously; certainly no 10x for x86 machines I think. On Raspbian Pi some cases are 10x, many are 5x but a few are actually slower. The key thing is that there is a decently intelligible framework into which more special case can be bult as needed and available. I suspect the code to search for a matching fast path might be improvable too, which will speed up the important small area blts.

And of course, a lot of drawing really ought to be via vector code anyway.
