Abstract:

The ultimate aim of performance evaluation is to improve the system efficiency. Overall
efficiency of the system is a combination of three factors: system functionality, performance
and cost. Whereas system functionality improvement and cost optimisation are usually
well understood and implemented the third factor of system performance is usually under
prioritized. The development and improvements on system functionality are naturally
driven by market requirements such as new features, compliance to common standards
and adaptation of new technologies. The evaluation of system functionality is available by
features benchmarking, etc. The evaluation of cost might be more complex due to the fact of
different criteria of system pricing and various methods of following the costs of system and
system maintenance. However, the cost of the system is also usually quite well evaluated and
optimised - it is naturally driven by market economics. The task of performance evaluation
followed with measurements and tests are usually performed only when certain performance
problems appear in a system. Additionally, the methodologies to measure and evaluate
system performance are not well known and understood. We believe that this approach
should be changed. The factors describing system efficiency are interleaved - the performance
can affect the cost of the system (usually long term maintenance costs) also the general system
functionality depends upon system performance, a system of poor performance may not be
able to accommodate new functionality or expand without difficult structural changes.
