An Empirical Study on the Performance Issues on the Clustered Client-Server Computing Environment

Abstract

In this paper, the performance of four computation models applied on a clustered computing environment is studied. A 3-tiered client-server architecture model is used as the baseline architecture for the study. An experimental cluster, using the off-the-shelf hardware and software components, was built and used to conduct the performance evaluations. The queries used in the study can be extended to numerous real-life applications. Hence the contribution of this study is mainly empirical, especially for those applications that have the similar settings. The alternative Multiple Application Servers, Multiple Database Servers (MAMDA) computation model which implements the application servers and database servers on the same PCs provides the best performance speedup, keeping the efficiency greater than or equal to 0.9.
