Is there a scale that shows the performance difference between the different collisions in U4?

Hi everyone.

I am just interested to know if there is a scale somewhere / documentation that shows clearly the difference in performance between the different collision types in Unreal 4?
I want to see exactly how much more performance intensive complex as simple is in relation to simple as complex and other types.
Also as you add meshes with collisions, is the increase in “cost” logarithmic or is it linear?
(Meaning is the increase just going up constantly or does it reach a point where it goes up a LOT suddenly)
Just wondering …
Does anyone know?

Thank you.
