Performance evaluation aim and approach Performance evaluation aims at forecasting system behaviour in a quantitative way. Whenever new systems are to be built or existing systems have to be reconfigured or adapted performance evaluation can be employed to predict the impact of architectural or implementation changes on the system performance. An important aspect of performance evaluation is performance measurement or monitoring. By monitoring the timing of certain important events in a system insight can be obtained in which system operations take most time or which system components are heavily loaded and which are not. Notice that a prerequisite for performance measurement is the availability of a system that can be observed measured . If such a system is not available measurement cannot be employed. As can easily be understood performance measurement will occur much more often in cases where existing systems have to be altered than in cases where new systems have to be designed. Another important aspect of performance measurement is the fact that the system that
