理论测试 .Net运算提升幅度较明显
SiSoftware Sandra Professional v2009能够对于被测系统进行方便、快捷、自动化的测试，是帮助我们了解被测系统各个子系统性能的不可或缺的测试软件。它的测试结果比较偏重于理论值，可重复性较好，便于帮助深入分析计算机系统的具体问题。

对比这两个测试平台在两个系统下的测试情况，我们看到Windows 7系统下，处理器相关的测试成绩有很小幅度的提高，而.Net部分的成绩提升则要相对明显一些，尤其是.Net算术性能测试部分，两个平台的成绩提升幅度都达到了20%左右，而相比起来，处理器算术性能测试部分的提升则可以用微弱来进行形容。而与处理器有关的其他部分，两个平台在两个系统下的测试成绩基本处在同一个水平，即使有提升也不到1%，基本可以忽略不计。
