We are getting very close to go-live and making sure that we have all the ground covered before we turn the switch on. In this chapter, we learned about performance tuning. We started the chapter with performance testing, understanding the importance of performance testing and tuning exercises in an implementation project. We went through the preparation, execution, and outcome of a performance testing and tuning exercise. Then, we looked at the various tools available for performance monitoring, testing, and troubleshooting the performance issues. To appropriately investigate and solve performance issues, you need to know about the causes. We analyzed the various factors which can cause performance issues in Dynamics AX and reviewed the guidelines and recommendations to avoid them. In the end, we talked about approaching the performance issues by understanding the issue in detail, creating a plan, and taking corrective action. We also talked about some real-life examples of performance issues and the approach taken to investigate and identify the root cause.

In the next chapter, we will talk about conducting system and user acceptance testing, as well as preparing the users for the new system through training and the change management process.
