Huh? It's the scrolling that takes time, not putting/removing sprites.
If Penguins worked this way (I think I remember it did) that was
definately badly coded...

I believe a timer routine is still required if you intend to do smooth
scrolling. Also, depending on how many enemies is on the screen (or
in the level), the AI might take some time too (if you have smart
enemies).
