Page layout VS Size layout

I wonder which one is more laggy when it come to this. Recently I want to make game where I need huge space whether I should add more size to the layout or should I add many page layout to do. so which is the better one?

A key concept is that sprites and textures are loaded into memory per layout. If you are not running into memory limitation issues, you probably don't need to worry. On the other hand, if you design with changing layouts in mind, your game can be more or less infinitely scalable.

The best way to take advantage of multiple layouts is when loading different tilesets, such as a snowy mountain area versus a desert area. You'll be able to load more detailed graphics per layout within your memory limitations.

Another consideration is CPU utilization such as pathfinding and other off screen processing. Separating by layout can sometimes solve issues with the CPU getting bogged down.
