Oh, what a bummer! I screwed up my example code and scrolled the colour memory instead of the character memory.
Hey, Stinaris. Indirect addressing is way slower that absolute indexed so it is not too surprising that it consumes that much time to do the copying. Furthermore, the "safe area" on the zero page is something like $D0..$E8. Consult with your copy of the Ultimate Map.
