After digging deeper into this issue, we found that this is a data intensive activity, the data is not in the cache, and results in a high paging rate.

对此问题进行深入分析后，我们发现这属于数据密集型行为，由于数据不在缓存内，因此造成较高的内存分页率。

High paging indicates a lack of RAM; a high scan rate (the sr column) shows a potential memory bottleneck.

较高的分页表示缺少RAM，较高的扫描速率(sr列)显示了潜在的内存瓶颈。

There is a problem of counting the page fault rate in the paging system. This paper analyzes the cause of the difference for the output in different textbooks.

在单段式虚拟存储器-请求式分页系统中，涉及到缺页中断次数的计算问题。从虚拟存储器的基本原理出发，分析了各种教材中有关计算结果不同的主要原因。
