The tests were conducted to find which parts of the system were being used when the tool was doing enough that it lagged severely. The intention was to find the system bottleneck for each app, so people speccing out a Mac can make an informed decision on which components will give them the best results, based on the tool they use.
The tests were NOT like for like — I kept adding rectangles until there was severe lagging. XD’s graphs show that the system has lots more power available, but there’s stalling or other issues that are stopping it from fully using the hardware. I realise this is a nuanced discussion, and there can be many reasons for certain results — seeing the CPU or GPU graphs pegged can be an indication of efficient OR inefficient use of the hardware. But, for this test, seeing the canvas lag and none of the graphs pegged almost certainly means the tool is not as optimised as it could be.
I will be doing some like for like tests very soon though. Those will show which tools are quick, and which are not. XD is definitely very fast, and I agree that Illustrator handles large numbers of objects very well.
