内核记录了对计算性分页重新分页的次数，以及对非计算性分页重新分页的次数。

The kernel maintains an indication of how many times it re-pages computational pages and how many times it re-pages non-computational pages.

如果非计算性分页的重新分页速度比计算性分页的重新分页速度高，那么 AIX 内核将选择计算性的分页和非计算性的分页进行操作。

If the rate of re-paging non-computational pages is higher than that of computational pages, the AIX kernel targets both computational as well as non-computational pages.
