A Workload Model for Benchmarking BPEL Engines

This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as success/fail rate, response times or round-trip delays which are then used to identify problems for scalability or usability aspects under heavy load.
