Generally, at that point, the device has reached a memory paging state, so killing some foreground processes is required to keep the user interface responsive.
通常，设备这时候已经到了内存分页状态(memory paging state)的地步，终止一些前台进程是为了保证用户界面的及时响应。
For performance reasons or when diagnosing a problem that you suspect might be swap space related, you often need a more interactive view of the memory and paging usage.

Paging a memory block out and back in from disk is significantly slower than accessing it directly from RAM, so you should generally avoid this practice.
与直接访问RAM中的内存块相比，把内存块交换到磁盘并交换回来要慢得多，所以一般情况下应该避免这种做法。

在创建或更新共享内存分区概要文件时，可以在内存配置部分中找到选择分页VIOS分区的选项。
This paging algorithm determines which virtual memory pages currently in ram ultimately have their page frames brought back to the free list.
这种分页算法可以确定对当前位于RAM中的哪些虚拟内存页面的页帧进行回收，并放回到空闲列表中。
It then commits just a part of the memory, and it is only for this part that the memory manager needs to allocate pages in real memory and in the paging file to back them up.
然后它仅仅提交一部分内存，这也是内存管理程序需要在实际内存和分页文件中分配页来支持它们的那一部分。
When a shared memory partition is activated, a suitable paging space device will automatically be selected.
在激活共享内存分区时，会自动地选择合适的分页空间设备。
If a cache is too big, then it can waste memory in the JVM and could result in low memory conditions or increased paging, both of which result in performance degradation.
如果缓存太大，则会浪费JVM中的内存，并且可能导致内存不足条件或增加内存分页，这两种情况都会导致性能下降。
When free physical memory starts getting low, programs that have not used recently are moved from ram to paging space to help release physical memory for more real work.
当空闲的物理内存较少时，可以将最近没有使用过的程序从RAM转移到分页空间，以帮助释放物理内存，从而完成更多的实际工作。
During the migration operation, all the memory that has been paged out to a paging space device is first read into real memory before being transmitted to the target server.
在迁移操作期间，换出到分页空间设备上的所有内存先被读入真实内存中，然后传输到目标服务器。
It calculates statistic averages for memory, paging, and CPU activity on a sampling period of a length specified by the user.
它将计算用户指定的采样时间内的内存、分页和CPU活动的统计平均值。
When adding a paging space device to the Shared memory pool, it will automatically be recognized as a common paging space device if the prerequisites mentioned previously are met.
在把分页空间设备添加到共享内存池中时，如果设备满足上述条件，会自动地识别为共用分页空间设备。
If the Shared memory partition has been configured to use redundant paging VIOS partitions, a common paging space device will be assigned.
如果共享内存分区使用冗余的分页VIOS分区，那么会分配共用的分页空间设备。
If you set the buffer pool size too high, then system memory usage will exceed the available physical memory, causing the operating system to spend more time paging the memory.
如果缓冲池大小过大，那么内存使用会超过可用的物理内存，从而导致操作花费更多时间对内存进行分页。
Obviously, administrators prefer to use physical memory rather than paging space, where the physical memory is available.
很显然，在可以使用物理内存的情况下，管理员更希望使用物理内存，而不是分页空间。
Generally, paging space should be one to two times real memory in size.
一般情况下，分页空间的大小应该是真实空间的一到两倍。
When modified working storage pages need to be paged out (moved from memory to the disk), they are written to paging space.
当需要将经过修改的工作存储分页替换出(从内存移动到磁盘)时，它们将被写入到分页空间。
These pages can be either RAM or paging space (virtual memory stored on disk).
这些页面可能是RAM、或者分页空间（即存储于磁盘中的虚拟内存）。
These pages can be either RAM or paging space (virtual memory stored on disk).
