3、要进行性能调优，一般情况下，可以从两方面进行调优：1,硬件配置方面；2,软件自身优化，此文主要从程序角度分析。SAP针对程序提供了静态和动态的分析工具，静态主要是通过语法检查来分析，tcode:SCI;动态为ST05,SE30,ST12,因ST12是ST05和SE30的结合体，此文将重点讲解ST12,它是将程序的执行过程记录（包括顺序，花费时间）下，从而可以查看哪些程序点消耗时间过长（后文将统称为：Trace）,然后进一步分析优化。1.1 参考资料ST12_Step_by_step.pdfABAPPerformanceTuning定义1.2 文档结构文档的各章节介绍的内容如下： 第2节性能分析
