Six weeks after you deliver your application to production, your users report that the application slows down in the afternoon. The application is almost completely unresponsive for some users shortly after

3:00 P.M. Other users do not experience this problem until later in the day.

You do not have access to the Production environment, but you do have access to AES. The production environment has three nodes and a load balancer.

You need to resolve this issue because a new division of the organization will start using the application next month.

How do you begin your research to diagnose the cause of the reported performance issue?
