A part Vs a Plane Mesh

[Testbot379]

(I’m very unsure about what topic to post this question on, So i choose this as felt more appropriate)

Let’s say we have a Generic Part and A plane which is imported from blender where one side isn’t visible (made up of only 2 triangles.)

Will it lag less if I spawn Spawn like 10 or 100 thousand Planes or Will it have similar results if I do the same with parts?

I am using this for a optimisation for blocky terrain generations like Minecraft.

If a part has more vertics than a plane where one side isn’t visible, then the part would lag the game with less amount of it than the Plane mesh.
