To evaluate a computing system, a method of producing quantitative measurements is required. The instruction rate of a processor and the time required for it to execute "benchmark" programs are commonly used as the measure by which such evaluations are made. In very small systems, parameters, such as the instruction rate, can be predicted by analysis. However, as systems grow in complexity, the respective analyses frequently become too cumbersome to produce accurate results. Empirical methods can be used to obtain the desired information in a straightforward manner, but usually require the use of an instrument to make measurements of the performance parameters. An important characteristic of such an instrument is that it remain passive with respect to the system under evaluation.
