Java 2 distributed object middleware performance analysis and optimization

Abstract

This paper is focused on the performance analysis, comparison and optimization of distributed object middleware for Java 2: RMI (Remote Method Invocation), CORBA IDL (Interface Definition Language) and RMI-IIOP (Remote Method Invocation on Internet Inter-ORB Protocol). The paper presents the following contributions to the research on distributed object performance. First, a detailed performance analysis is provided with the comparison. These results help to understand how the models perform. Second, an overhead analysis has been done, which explains why there are differences in performance. Third, optimizations and improved performance for RMI-IIOP and CORBA IDL are presented. These show considerably better performance in all areas compared to the original versions.
