Two problems in Web Services composition has been tackled in this paper: firstly, decoupling flow execution and Web Services invocation in Web Services Composition Execution Engine--WebJetFlow; secondly, changing services invocation model of Service Proxy from synchronous invocation model to pure asynchronous invocation model. Then NS2 has been adopted to test the performance of WebJetFlow under five different circumstances as well as the performance of WebJetFlow with Service Proxy and without Service Proxy respectively. The simulation results show that the access throughputs of WebJetFlow with Service Proxy are larger than those without Service Proxy under the same thread resources. Moreover, decoupling flow execution and Web Services invocation and using pure asynchronous invocation model greatly increase the concurrence of flow execution, enhance the utilization efficiency and improve the performance of WebJetFlow.
