Performance Analysis

Once given the typical scenarios from the requirement document, the system can be designed to meet performance objectives. Different system architectures will yield different predicted performance characteristics for each typical scenario. Depending on the usage frequency of the scenarios in the system, each architecture will have benefits and drawbacks with advantages and disadvantages. The trade-offs are then weighted to establish the system architecture. Frequently a system is designed to give fast response to an action initiated by a human customer at the expense of having to do more complex systems work such as including indexes, cache management, and predictive pre-calculations.
