Aspect: Tune
The Tune aspect of the performance testing lifecycle is the heart of the performance testing project. While everyone hopes that no tuning will be required, this is very rarely the case. This phase of the project is a collaborative effort between the performance engineer and the developers/administrators of the system. These groups, working together, are able to detect performance issues and tune them more effectively than either group could alone. The effectiveness of this activity directly correlates to the project´s ability to stay on schedule and meet the documented acceptance criteria.
