The aim of the exercising is to reduce the entire volume of resources utilised, and not to minimize the peak resources.
This insight will let you know what exactly is at the moment causing slowdowns, what on earth is resulting in superior useful resource utilization, and what is limiting issue for your long run database software scalability.
