Answer 2

There are several handlers in APIM, through which all API calls are going. Eg. Authentication, Throttling, CORS etc.

You can enable analytics in APIM and see a latency breakdown graph among stages. See Figure 9 of this article. Then you can identify if there are any handlers which cause a large latency. Then we can decide how to fix that.
