Performance Tuning

A developer goal is to maximize system performance. By scaling resources, you will, to a point, increase performance. In addition to managing an application’s resource utilization, developers must examine the application itself, beginning with the program code and including the objects used, such as graphics and the application’s use of caching.

To start the process of performance tuning, you should first look for existing or potential system bottlenecks. After you correct those, you should focus on the 20 percent of the code that performs 80 percent of the processing—that’s the location that will provide you the biggest return on your system tuning investment.
