摘要
分布式文件存储系统的性能测试不同于普通的文件系统性能测试。首先,需要根据系统支持的操作确定测试的benchmark,然后,需要根据系统的设计规模对多用户并发访问系统的情形进行模拟。在“燕星”分布式文件存储系统的性能测试中,对Andrewbenchmark进行改造,确定了测试的benchmark;基于RMIcallback机制,模拟了500个用户并发访问系统的情形。并将测试结果与NFS进行了对比,结果表明,“燕星”系统具有良好的实用性能。
The performance test of Distributed file storage system varies from that of common file system.First,the suit-able benchmark should be chosen,second,the case of vast users simultaneously access should be simulated.To quantify the performance of Yanxing System,the authors run the modified Andrew benchmark and simulate the case of500user access the system simultaneously based on the mechanism of RMI callback.The testing result is compared with NFS,which shows that the authors' system has fine practicability.
