SiSoftware Sandra Pro Business 2009
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。从Sandra 2007开始支持SSE4指令集。SiSoftware Sandra所有的基准测试都针对SMP和SMT进行了优化，最高可支持32/64路平台，这也是我们选择这款软件的原因之一。

SiSoftware Sandra对比
DELL PE 1950 III服务器采用的E5420处理器频率为2.50GHz，比我们采用266GHz E5420处理器的DELL PE2900 III基准平台略低好，因此处理器理论性能也低一些，不过在Inter-Core Bandwidth和Cache/Memory Bandwidth反而比我们的基准平台要高，这个可能跟主板有关。
