Mesh collider impact?

Hi does the mesh collider have a bigger impact on on ram use. I need to place thousands of trees and would rather use mesh colliders on them but memory is a big concern so what if any is the ram situation between a mesh or simple collider thx.

 

It affects ram, performance and loading times from my experience. A while ago I wrote this answer:

I recommend you check both cases with the Unity Profiler:

Hey Peter
Thx for the links didn't really see anything about its ram use but def don't want to add to scene load times and I imagine that instantiating a mesh collider obj would probably also then take additional time?.
Guess it back to best approximation with as few simple colliders. as possible.
Thx again
