World size performance difference

I read sometime in the posts “I have a very large world of … width”. It might be a silly question now. Does it matter if my if my world is say 5000 or 50 width with the same amount of vertices world mesh in it but scaled? Cameras, light and so on would have to be adjusted for correct max/min of course.
Would the performance be any different? Would the physics engines act any different?

I suppose there is a limitation on the low side for float numbers accuracy. In general I try to keep my world to correspond to meters as its more intuitive. Is that the right approach?

While Babylon units are relative this approach is completely right and usually helps to avoid edge cases.

thanks @labris Any idea about first question, performance difference for “large” and “small” world?

As far as you avoid edge cases there is no difference at all.
