A system with a smaller page size uses more pages, requiring a page table that occupies more space. For example, if a 2 32 virtual address space is mapped to 4 KiB (2 12 bytes) pages, the number of virtual pages is 2 20 = (2 32 / 2 12). However, if the page size is increased to 32 KiB (2 15 bytes), only 2 17 pages are required. A multi-level ...
In computing, commit charge is a term used in Microsoft Windows operating systems to describe the total amount of virtual memory of all processes that must be backed by either physical memory or the page file. [1] Through the process of paging, the contents of this virtual memory may move between physical memory and the page file, but it cannot ...
Since PageDefrag only affects a few files, it takes a relatively short time to run when compared to entire-disk defragmenters such as Windows Defrag, so long as the page file is not fragmented. If the page file is fragmented, PageDefrag can take as long or longer than Windows Defrag. However, a defragmentation of the page file can improve ...
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]
In computing, a page fault is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space. Furthermore, the actual page contents may need to be loaded from a back-up, e.g. a disk.
The entries in the page directory have an additional flag in bit 7, named PS (for page size). If the system has set this bit to 1, the page directory entry does not point to a page table but to a single, large 2 MB page (Page Size Extension).

In the default configuration of Windows, the page file is allowed to expand beyond its initial allocation when necessary. If this happens gradually, it can become heavily fragmented which can potentially cause performance problems. [15] The common advice given to avoid this is to set a single "locked" page file size so that Windows will not ...
