Service-oriented systems are designed for interconnectingwith other systems. The provided services face timing con-straints, the so-called latencies. We present a high-level per-formance evaluation technique that can be used by a systemdesigner to obtain distributions of these latencies. This tech-nique is capable of capturing nondeterministic, probabilisticand real-time aspects in one go. Under the hood, the tech-nique is equipped with two mechanisms: (i) selection of theright abstraction of the model (to prevent a state space ex-plosion) by evaluating the performance of executing modelsof different complexities; and (ii) an efficient algorithm inwhich basic estimates, simulation, and (probabilistic) modelchecking are combined. We illustrate our approach with ancase on image processing of interventional X-ray systems.
