This is a quick and dirty app to compare benchmark of concurrentPerform and TaskGroup (vs serial execution), when running CPU intensive calculations.
Note:
-
The cooperative thread pool on simulators is highly constrained, so most illustrative results can be see when you run this on physical devices.
-
If you profile the app with Instruments, using the “Time Profiler” template (which includes “Points of Interest” tool), you can graphically see the performance.
