电子商务软件负载能力评估的实例分析

负载能力是表征电子商务软件性能的一项重要标准。负载能力的评价方法包括在线系统的数据统计和估算、程序测算、基于测试的评估方法等。其中，基于测试的评估方法越来越受到人们的重视。本文以一个小型电子商务系统为例，采用基于测试的评估方法进行了系统的负载能力分析。结果表明，对于以优化为目标的系统评估，可以在优化后采用逐步细化的负载测试方式得到最佳负载预测数据。同时，在负载能力的评估过程中，需要根据系统的主要功能来选择合理的评估指标。

Case study of load ability evaluation of e-business software

The loading capacity is an important measure of e-business software. Three typical load-testing methods are data statistic and estimation of online system, program calculation, test-based evaluation. Now, people pay more and more attention to the test-based evaluation. This paper demonstrates this evaluation method by an example a small e-business system, and its load ability is analyzed in detailed. The results show that the evaluation aiming to optimization can get the best forecast load data by using load testing step by step. And on the process of load ability evaluation, we should choose reasonable measures carefully according to main functions of the under-evaluation-system.
