Memory Cost of Convex Collider

I'm building game with physics collider scalable, I made convex collider rebuild when their scale changed. So, collider of each entity is unique, referencer count of blobasset is aways 1. Of course this is a waste of memory and maybe performance too. My question is for convex collider, when I created from a bunch of points, how much memory cost of created collider structure?

 

Along with points, is there additional polygon / face structure cost memory? In general, how much times memory cost comparing to original points data?

 

You can use the Collider MemorySize field to get the memory cost.
