The required disk space may be easily allocated on systems with more recent specifications (i.e. a system with 3 GB of memory having a 6 GB fixed-size page file on a 750 GB disk drive, or a system with 6 GB of memory and a 16 GB fixed-size page file and 2 TB of disk space).
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, 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.
Windows 7 also supports the newer exFAT file system. As the ReadyBoost cache is stored as a file, the flash drive must be formatted as FAT32, NTFS, or exFAT in order to have a cache size greater than FAT16's 2 GB filesize limit; if the desired cache size is 4 GB (the FAT32 filesize limit) or larger, the drive must be formatted as NTFS or exFAT.
With PAE; 2 MB pages. 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).

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 performance much more than defragmentation of the Registry will. PageDefrag does not defragment the contents of the registry files, only the placement of these files on the hard drive. Other ...
[4] [5] File copy operations are speculated to be one area where Vista performs better than XP. [clarification needed] In a test run by CRN Test Center, a 1.25 GB file was copied from a network share to each desktop. For XP, it took 2 minutes and 54 seconds, for Vista with SP1 it took 2 minutes and 29 seconds.
