由于后端应用系统的复杂性，业界常用的负载工具很难模拟后端系统的运作。对于应用系统来说，仅通过前 端模拟用户的方式来定位后端应用系统的问题总会差强人意，因此本文提出一种针对后端应用系统的性能测试方法，得出后 端系统的最大处理能力以及扩容的方法，进而提高整个应用系统的性能。

The complexity of the back-end application systems makes it difficult to be simulated by the common load tools. For the application system, it is barely satisfactory that only using the front-end user simulation mod to solve the problems of back-end application system. This paper presents a performance testing method for back-end application system, obtaining the maximum processing capacity and capacity expansion method, and improving the performance of the whole application system.
