High Performance Approach for Server Side SOAP Processing

Web services, with an emphasis on open standards and flexibility, can provide benefits over existing capital markets’ integration practices. However, Web services must first meet certain technical requirements, including performance, security, and so on. Based on extensible markup language (XML), Web services inherit not only the advantages of XML, but its relatively poor performance, which makes it a poor choice for many high-performance applications. In this article, a new approach is proposed to improve Web services performance. Focusing on avoiding traditional XML parsing and Java reflection at runtime, this article presents a service-specific simple object access protocol (SOAP) processor to accelerate the execution of Web services. Moreover, the SOAP processor embeds several cache implementations and uses a novel adaptive cache mechanism, which can choose an optimized cache implementation dynamically. Through the experiments in this article, it is to be observed that the proposed approach can achieve a significant performance gain by incorporating the SOAP processor into the SOAP engine.
