This article also discusses the limitations of using memory beyond the 4-gigabyte GB range that is inherent to bit operating systems.
In Windows Server , PAE is automatically enabled only if the server is using hot-add memory devices. The more programs and, therefore, more processes that run, the more memory you commit up to the full 2 GB of address space. When this situation occurs, the paging process increases dramatically and performance may be negatively impacted. This reduces the need to swap the memory of the page file and results in increased performance.
The program itself isn't aware of the actual memory size. All the memory management and allocation of the PAE memory is handled by the memory manager independently of the programs that run. A program that requests 3 GB of memory is more likely to be able to have more of its memory remain in physical memory rather than be paged out. In this case, the operating system doesn't use any memory in excess of 16 GB.
This behavior is caused by kernel virtual memory space considerations. AWE is a set of application programming interfaces APIs to the memory manager functions that enables programs to address more memory than the 4 GB that is available through standard bit addressing.
AWE enables programs to reserve physical memory as non-paged memory and then to dynamically map portions of the non-paged memory to the program's working set of memory. This process enables memory-intensive programs, such as large database systems, to reserve large amounts of physical memory for data without having to be paged in and out of a paging file for usage. Instead, the data is swapped in and out of the working set and reserved memory is in excess of the 4-GB range. Would you like to install the Microsoft Download Manager?
