I am new to performance in general and have been learning Perfview.

I was curious how to go about using PerfView to test the performance of my APIs hosted on ASP.NET Core APIs?

I was wondering if I could use the profiler that picks up the stack trace on App Insight and just have it read the information there to drill it down and solve any performance issues.

Or is it better to get on the actual server itself where it is hosted and run the API endpoints?
