SiSoftware Sandra是一款可运行在32bit和64bit Windows操作系统上的分析软件，这款软件可以对于系统进行方便、快捷的基准测试，还可以用于查看系统的软件、硬件等信息。我们使用了SiSoftware Sandra的2009版，它可以支持各种最新的CPU指令集，并能良好地支持多核、多线程，我们主要用其来评估平台的理论计算性能。

在这项测试中，戴尔PowerEdge 2900III由于处理器规格及内存容量的优势，许多项目都占据优势，TS100-E5的成绩在部分项目中只有它的一半，大多数项目成绩达到了它的70%左右，考虑到两款服务器间配置的差异较大，这样的结果还可以接受。让我们觉得欣慰的是，在内存相关的测试中，凭借着DDR2 800的较高频率，TS100-E5还是占据了略微的带宽优势；而且由于只有单条内存，在延迟测试中的成绩也较对比服务器略好一些。
