这指示DB 2将一些数据加载到Windows的大页内存中。
This instructs DB2 to load some of its data into Windows' large page memory.
使用大页主要是为提高内存访问频繁的应用程序的性能。
Large page usage is primarily intended to provide performance improvements to memory access intensive applications.
对于具有大内存需求的情况，大页支持可以改善后援转换进程的性能。
For instances with large memory requirements, large page support can improve performance for the look-aside translation process.
注意这里的显示，进程可能有一个大的地址空间，但是很少见，就是说小的地址空间的区域(页面)通过页表指向物理内存。
Note that as shown here, a process may have a large address space, but it is sparse, meaning that small regions (pages) of the address space refer to physical memory through the page tables.
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.
为需要内存很多的应用程序提供了大页(largepage)支持，允许使用16MB的页大小，同时仍支持传统的4K b页大小。
Large page support is provided for memory intensive applications, allowing 16mb page sizes while still providing the traditional 4kb page sizes.
从磁盘读取相像大小的数据到内存，应用大的页大小比运用小的页大小耗费的工夫更少。
Transferring the same amount of data from disk to memory often requires less time with larger pages than with smaller pages.
从磁盘读取相像大小的数据到内存，应用大的页大小比运用小的页大小耗费的工夫更少。
