This chapter shows how you can spend less time tuning in a larger performance environment by first tuning in a modest-sized, smaller environment. In this smaller environment, you can complete more fix-test cycles per day, which greatly accelerates the overall tuning process.

The objectives of this chapter are:

• Learn how to design load tests that will run in a very small computing environment (like your desktop), effectively turning it into an economical performance tuning lab.
• Learn how to graph CPU/RAM consumption of individual processes over time. ...
