Benchmark Testing Methodology

This benchmarking technique is based on the scientific method. A repeatable environment will be created in which the same test, run under the same conditions, will yield comparable results.

Benchmarking can also begin by running the test application in a normal environment. As a performance problem is narrowed down, specialized test cases can be developed to limit the scope of the function that is being tested and observed. The specialized test cases need not emulate an entire application in order to obtain valuable information. Start with simple measurements, and increase the complexity only when warranted.

Characteristics of good benchmarks (or measurements) include:

As with any benchmarking, a scenario must be devised and then executed. The following information applies these concepts to the DB2 environment.
