可以使用VMM的页面置换算法来选择要重新分配页帧的虚拟内存页面。
The virtual memory pages whose page frames are to be reassigned are selected using the VMM's page replacement algorithm.
改进页面置换算法，可以降低页面失败率，从而有效地提高系统性能。
Improving virtual memory page replacement can reduce page fault rate, and therefore improve the performance of the system.
VMM一直在后台运行，尝试使用前面介绍的页面置换算法偷取最近没有引用过的页帧。
VMM is constantly lurking and working in the background trying to steal frames that have not been recently referenced, using the page replacement algorithm discussed earlier.
选择一个页面来交换存储的过程被称为一个页面置换算法，可以通过使用许多算法(至少是最近使用的)来实现。
The process by which a page is selected to swap to storage is called a page-replacement algorithm and can be implemented using a number of algorithms (such as least recently used).
在对有大量内存的系统进行扫描时，因为页面置换算法始终寻找空闲帧，所以需要扫描的页帧数量非常大。
Because the page replacement algorithm is always looking for free frames while it is doing its scanning on systems with a lot of memory, the number of frames to scan can be significant.
VMM 提供了一种页面置换算法，该算法用于分配页帧，以及确定应该将当前RAM 中的哪些虚拟内存页面的页帧置换回空闲列表。
The VMM has a page-replacement algorithm, which assigns the page frames and determines exactly which virtual-memory pages currently in RAM will have their page frames brought back to the free list.
以前，它的工作方式非常简单：如果您的文件页面 (numperm%)大于maxperm%，那么页面置换算法将仅替换文件页面。
The way it worked in the past was actually quite simple: If your file pages (numperm%) were greater than the actual maxperm%, then the page replacement would only steal file pages.
