How to find resource intensive operations in an ASP.NET MVC application on IIS?

Question

IIS

There is a Windows Server and a site on ASP.NET MVC, which is running on IIS.
There is a suspicion that the application does not optimally use resources, it devours too many of them.
It is required to find out which operations/functions are in fact resource-intensive, which take up a lot of server time from the server.

Answer 1

At 15 studios, there is already an absolutely human profiler.
If you don’t like the profiler from the studio, then you can use jetbrain.

Answer 2

Glimpse is also an option, it is very much nothing.
