我有这个C++代码：
将 10000 个初始化的学生生成到容器中。按字母顺序对学生进行排序。将学生分为通过和失败。将结果输出到控制台。
为了提高效率，使用不同的容器类型（静态和非静态）来计时执行，以保持和迭代10000名学生。
没有从文件中读取任何内容，所有学生数据都包含在代码中。
以下是正在使用的两个CPU之间的基准比较，从结果中应该可以明显看出一个是新的，一个是旧的：

以下是比较每个 CPU 上的执行时间的结果。知道为什么新CPU被旧CPU抛在后面吗？:

Opteron 170（较旧）计算机的二级缓存是较新计算机的两倍，这将对非常占用大量内存的操作产生很大影响。 当被访问的两个项目彼此靠近时，缓存效果将最明显---就像使用矢量---时一样，这正是我们在这里看到的。
