基于ORB／Java分布式中间件的性能

Performance of ORB/Java-Based Distributed Middleware

对ORB／Java2使用分布式对象中间件性能进行了分析研究，其中详细研究了中间件RMI、IDL与RMI—ⅡOP（基于Intemet的ORB问协议远程方法调用1使用性能。用比较方法进行性能的详细分析。分析结果有利于对几种模型性能进行归纳并改进。论文详细分析了产生不同性能影响的原因。最后得出RMI—ⅡOP与IDL的性能优化与性能改善的方法。

This paper is focused on the performance analysis of distributed object middleware for ORB and Java2： RMI （Remote Method Invocation）, IDL and RMI-ⅡOP （Remote Method Invocation on Intemet Inter-ORB Protocol）.The paper presents the following contributions to the research on distributed object performance. A detailed performance analysis is provided with the comparison, These results help to understand how the models perform, An overhead analysis explains why there are differences in performance. Final the optimizations and improved performance for RMI-ⅡOP and ORB IDL are presented.
