摘要： 针对远程容灾系统结构多样、缺乏适用于测试的技术性能指标和不易进行性能测试的现状，设计一种性能测试方法，通过I/O吞吐量、CPU利用率、响应时间和数据备份时间等指标反映容灾系统的性能。利用该方法对远程异步容灾系统测试时，测试数据显示容灾系统对应用服务器响应时间的影响为零，符合异步容灾系统的技术特点，证明该方法适用于容灾系统性能测试。

Abstract: The Remote Disaster Tolerant System(RDTS) is difficult to test, because it has diverse structure and lacks suitable benchmark for test. A method of performance test is presented in this paper. Through I/O throughput, CPU utilizatI/On, response time and data backup time, the method can reflect the performance of RDTS. When this method is used to test RDTS, test data show that the RDTS doesnot make a difference to respond time of applicatI/On servers, which accords with the technical characteristics of RDTS and proves that the method fits for the performance test of RDTS.
