In the first chapter, I stressed the importance of having a performance baseline that you can use to measure performance changes. In fact, this is one of the first things you should do when starting the performance-tuning process, since without a baseline you will not be able to quantify improvements. In this chapter, you will learn how to use the Performance Monitor tool to accomplish this and how to use the different performance counters that are required to create a baseline.
Specifically, I cover the following topics:
The basics of the Performance Monitor tool
How to analyze hardware resource bottlenecks using Performance Monitor
How to retrieve Performance Monitor data within SQL Server using dynamic management ...
