随着程序对该文件进行读写操作，AIX内核将该文件的数据作为非计算性的永久存储分页在内存中进行缓存。
As a program does reads and writes to the file, the AIX kernel caches the file's data in memory as non-computational permanent storage pages.
当maxperm是严格限制的时候，即使有可供使用的空闲内存，内核也不允许非计算性分页的数目超出maxperm的限制。
When maxperm is a strict-limit, the kernel does not allow the number of non-computational pages to exceed maxperm, even if there is free memory available.
MaxCPUTime是按秒计算的CPU使用时间的最大百分比(运行内核及非内核代码，包括IO等待时间)。
Max CPU time is the maximum percentage of time in seconds that the CPU was in use (running both kernel and non-kernel code, including IO wait time).
这两个可调参数用于指出AIX内核应该使用多少内存来缓存非计算性的分页。
These tunable parameters are used to indicate how much memory the AIX kernel should use to cache non-computational pages.
这意味着，AIX内核不允许非计算性的客户端文件缓存超出maxclient限制的范围（也就是说，AIX 内核不允许numclient 超出 maxclient）。
This means that the AIX kernel does not allow the non-computational client file cache to exceed the maxclient limit (that is, the AIX kernel does not allow numclient to exceed maxclient).
这意味着，AIX内核不允许非计算性的客户端文件缓存超出maxclient限制的范围（也就是说，AIX 内核不允许numclient 超出 maxclient）。
This means that the AIX kernel does not allow the non-computational client file cache to exceed the maxclient limit (that is, the AIX kernel does not allow numclient to exceed maxclient).
