I'm no expert but that looks more like one totally unoptimized operation.

Anyway, sna has been extremly fine tuned for a long time now. Just look at only the amount of work they put into it: http://cgit.freedesktop.org/xorg/dri...?qt=grep&q=sna or some of the insane optimisations: http://cgit.freedesktop.org/xorg/dri...t=grep&q=optim

Glamor being much younger probably hasn't seen that much optimization.
