摘　　要：JMS定义了Java访问消息中间件标准的和统一的接口,克服了RPC中间件技术的同步通信、紧密耦合等的局限性。消息驱动Bean(MDB)组件作为一种完善的JMS客户机,很好地利用了已有的EJB和J2EE技术。本文使用JMSPTP扇出体系结构,以消息驱动Bean组件作为消息异步消费者,并且以消息大小、应答模式、线程数、JVM选项等作为影响吞吐量的4个因素,对其通信性能进行了测试。采用方差分析、最小正规二次无偏估计等数理统计方法分析实验数据,获得了各个因素及其各个水平对吞吐量边际均值的具体影响程度,为通信性能的增益提供了有效的参考价值。JMS （Java Message Service）defined the standard and uniform interface of message oriented middleware （MOM） for Java and has overcome the drawbacks of synchronous communication and compact coupling of RPC （remote procedure call）middleware. AS a kind of JMS client, message driven bean （MDB）utilized the perfect technology of EJB and J2EE. In this paper, by using MDB as an asynchronous message consumer and JMS PTP fan-out architecture, communication performance test has been performed according to relationship between the four factors of message size, acknowledge mold, threads number, JVM option and the dependent variable （throughput）. Experimental data were analyzed by the statistic methods of ANOVA （analysis of variance）and MINQUE （Minimum Norm Quadratic Unbiased Estimation）. Simulation results indicated that communication performance could be improved according to estimated marginal means of throughput affected by each factor and its levels.
