Can I make worlds take up less resources?

On my creative server, I want it so that each player has a world so that they have their own individual space. There will be two types of plots, business/store plots and personal plots. With personal plots, only their friends and the owner can go to the world however with business/store plots when they open the plot anyone can join or only people they authorize can join, in accordance with their plot settings.

How could I make it so that worlds take up less resources?

Thanks,

What is taking up most of the resources are the loaded chunks. If you're worried about memory-space/performance, either reduce the amount of loaded chunks to 1 or 2 per world (by canceling chunk loading for anything outside of the main plots) or try merging some of the worlds (If each plot is only supposed to be 16x16 or 32x32, you can merge all of the worlds into one world, and build a wall around each chunk so that they can only exist in each small cell.)

 

Oh, ok Thanks
