    PageDefrag runs on Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003. Though the website erroneously [ 1 ] says "runs on Windows XP (32-bit) and higher (32-bit), Windows Server 2003 (32-bit) and higher (32-bit)", the tool cannot defragment the pagefile on Windows Vista, Windows 7, or Server 2008; it is able to defragment ...

    4-level paging of the 64-bit mode. In the 4-level paging scheme (previously known as IA-32e paging), the 64-bit virtual memory address is divided into five parts. The lowest 12 bits contain the offset within the 4 KiB memory page, and the following 36 bits are evenly divided between the four 9 bit descriptors, each linking to a 64-bit page table entry in a 512-entry page table for each of the ...

    en.wikipedia.org/wiki/Second_Level_Address...

    It is also helpful to use large pages in the host page tables to reduce the number of levels (e.g., in x86-64, using 2 MB pages removes one level in the page table). Since memory is typically allocated to virtual machines at coarse granularity, using large pages for guest-physical translation is an obvious optimization, reducing the depth of ...

  5. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    A process can store data in memory-mapped files on memory-backed file systems, such as the tmpfs file system or file systems on a RAM drive, and map files into and out of the address space as needed. A set of processes may still depend upon the enhanced security features page-based isolation may bring to a multitasking environment.

  6. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    The bottom bits of the address (the offset within a page) are left unchanged. The upper address bits are the virtual page numbers. [3] Most MMUs use an in-memory table of items called a page table, containing one page table entry (PTE) per virtual page, to map virtual page numbers to physical page numbers in main memory. Multi-level page tables ...

  8. Physical Address Extension - Wikipedia

    en.wikipedia.org/wiki/Physical_Address_Extension

    The page table structure used by x86-64 CPUs when operating in long mode further extends the page table hierarchy to four or more levels, extending the virtual address space, and uses additional physical address bits at all levels of the page table, extending the physical address space.
