Large Page Memory的意思|示意

Large pages can accommodate more memory in fewer actual pages, so as more large pages are used, more memory can be referenced through the TLB than with smaller page sizes.

大内存页可以用更少的实际页来提供更多的内存，相当于较小的页大小，使用的大内存页越多，就有越多的内存可以通过TLB引用。

However, for systems in which a large number of processes are running, storing page tables in high memory can be enabled to squeeze more memory out of the low memory area.

不过，对于那些在大量进程在运行的系统来说，将页表存储到高端内存中可以在低端内存区域挤出更多的内存。

Several platforms provide the ability to establish a large contiguous section of memory using memory pages that are larger than the default memory page size.

一些平台支持建立一大块相邻的内存区，以便能够使用比默认内存分页大小更大的内存分页。

The main purpose for large page usage is to improve system performance for high-performance computing applications or any memory-access-intensive application that uses large amounts of virtual memory.

使用大页面的主要目的是，提高高性能计算应用程序或使用大量虚拟内存的任何内存访问密集型应用程序的系统性能。

However, if you make it too large, you can waste valuable memory resources on your managed system due to the size of the page table created for the partition.

然而，如果将它设置的太大，则可能会由于为该分区创建的页表大小而浪费所管理系统上的宝贵内存资源。

Assuming a large page size of 4 MB is used in the same example from above, that same 1 GB of memory could be mapped with only 256 page-table entries instead of 262,144.

假定在前面的中使用页大小为4 MB的大内存页，同样1 GB内存只用256个页表条目就可以映射，而不需要262,144个。
