CanvasScaler.Update() causes slowdown according to Unity Profiler

I noticed while running my game in the editor with while using a CanvasScaler script on my UI Canvas, that the profiler attributes the spikes and slowdown to CanvasScaler.Update(), which inside calls Screen.get_dpi.

I was wondering if it was possible to control how frequently the CanvasScaler.Update() is called, and if not, is there a way to create my own script that reproduces what the CanvasScaler does?

 

The UT guys let slip that this is purely an editor thing and should not occur in builds. It's completely normal.

 

Ok. Does that mean I'm not able to have the game run smoothly in the editor because besides that everything else's millisecond amount is low in the editor.

 

If it's causing a concern for you, then I'd create a sample project and submit an issue using the Unity bug tracker. The above was just a statement they made on another post recently.
