This question already has an answer here:

Is there a way/tool that could basically report what ArcMap 10.2 is doing?

I can't really explain it, so I will show you what I mean. Now mind you it doesn't have to be exactly like this.

Query Basemap (150ms)
Draw Basemap (300ms)
Query Layer1 (100ms)
Draw Layer1 (200ms)
Query Layer2 (50ms)
Draw Layer2 (3000ms)

The point of this would show me that Layer2 is taking 3 seconds to draw, so maybe I could change the symbolism to make it faster.

This question was merged with Measuring draw time of layer in ArcMap? because it is an exact duplicate of that question.
