It isn't.

50Hz scrolling, also 8-way scrolling, is negligible and needs only a few raster lines per frame when using the right technique. In the worst case you will copy-blit a few tiles in the border. Usually there are many more tiles to blit just for tile-animations on the screen. The biggest impact have numerous big BOBs in the scene, which have to be blitted masked with all four channels and an extra-word for shifting.

But not so much fun.
