【摘要】 性能工程(SPE)是对软件进行性能控制的有效方法。该方法通过在软件开发的不同阶段建立相应的性能模型对软件的性能进行评估和控制。由于该过程中需要建立不同模型并采集模型所需的数据,工作量比较大。针对分布式系统的特点,对SPE中分布式系统性能评估模型进行了改进,提出了一种简单有效的性能评估模型,避免了对性能多次建模。此外结合一个应用案例介绍了该评估模型的使用过程。更多还原

【Abstract】 Software performance engineering(SPE) is an effective approach to control software performance.This approach is used to evaluate and control performance by building performance models at different stages of software development.During this process,not only different models need be built but also much data need be collected,so work is hard.According to the charac-teristics of the distributed system,the evaluation model of the distributed system in SPE is improved and a simple and effective model are presented to avoid modeling performance many times.Furthermore,the performance evaluation model is introduced through the application case.更多还原
