Landscape creation - best performance settings

Hi fellow developers,

So I’ve read the technical guide on landscape creation, but now I’m wondering about some settings.
From what I read, limiting the number of components equals to better performance.
On the bottom of the documentation page there is a table with some examples, the upper record is about a terrain of 8129x8129 in size, with** 1024 total components (32x32).**
Say I’d want to create a huge terrain (64km²) of that size, I see it’s also possible with 256 total components, using more quads for the section size.
Which of the following settings would be the best regarding performance? The scale would be 100.0.

Configuration 1
Section size: 127x127 Quads
Sections per component: 2x2 Sections
Number of components: 32x32
Overall resolution: 8129x8129
Total components: 1024

Configuration 2
Section size: 255x255 Quads
Sections per component: 2x2 Sections
Number of components: 16x16
Overall resolution: 8129x8129
Total components: 256
