Map Sizing

I been experimenting with map sizes. I just want to know what is to big. I’m making a map that is: Section size 255×255 quads, 2x2 sections per component, 16×16 components. Changing the x,y, and z scale to 300. I was wondering since ark does a streaming system by section would that be to big, and will I have performance issue with that size?

For Multiplayer Maps it is recommended to use an overall Resolution of 2017x2017 or lower.
Here´s a link you can check out for that purpose. Landscape Technical Guide | Unreal Engine Documentation
