scaling in unity 5 affecting performance?

Unity Engine
1

so after reading many posts on the internet saying that you should aim for having transform.localscale = Vector3.one, i wrote a script that at the start of the game resizes all meshes and colliders according to their transform.localscale and then set the transform.localscale to 1,1,1.

but i see no difference in the performance of my game. is in unity 5 at least in theory any benefit to not resizing objects via transform.localscale or was this just a unity 4 thing?

There is no benefit in 5 to keeping the scale uniform performance-wise. You may want to keep parents a uniform scale if child objects will scale, because when rotated it will cause skewing. But for performance, there is no benefit.

It was just a 4 thing.
