GeneratePhysicRepresentationForMesh causing slow down

[BetaJester]

Hi there

I've got a simulation where we create Obi Cloth balloons which move around the screen. However, whenever we spawn a new bubble and use GeneratePhysicRepresentationForMesh we're getting significant slow down. 

For reference we call:  

Code:

yield return balloon.GetComponent<ObiCloth>().GeneratePhysicRepresentationForMesh();

inside the spawn coroutine. 

I've tried threading the code, but GeneratePhysicRepresentationForMesh needs to be on the main thread. Is there a way it is meant to be used which means it has a minimal performance hit?
