PetStore-WS : measuring the performance implications of web services
Kai S. Juse, Samuel Kounev, Alejandro Buchmann · 2003
Web Services are increasingly used to enable loosely coupled integration among heterogeneous systems but are perceived as a source of severe performance degradation. This paper looks at the impact on system performance when introducing Web Service interfaces to an originally tightly coupled application. Using two implementation variants of Sun's Java Pet Store application, one based strictly on the J2EE platform and the other implementing some interfaces as Web Services, performance is compared in terms of the achieved overall throughput, response times and latency.
