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 ...
Page faults degrade system performance and can cause thrashing. Major page faults on conventional computers using hard disk drives can have a significant impact on their performance, as an average hard disk drive has an average rotational latency of 3 ms, a seek time of 5 ms, and a transfer time of 0.05 ms/page. Therefore, the total time for ...
In this case the page is paged out to a secondary store located on a medium such as a hard disk drive (this secondary store, or "backing store", is often called a swap partition if it is a disk partition, or a swap file, swapfile or page file if it is a file). When this happens the page needs to be taken from disk and put back into physical memory.
By default, the size of each page remains as 4 KB. Each entry in the page table and page directory becomes 64 bits long (8 bytes), instead of 32 bits, to allow for additional address bits. However, the size of each table does not change, so both table and directory now have only 512 entries.
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 ...

The minimum cache size is 250 MB. In Vista or with FAT32 formatting of the drive, the maximum is 4 GB. In Windows 7 or later with NTFS or exFAT formatting, the maximum cache size is 32 GB per device. Windows Vista allows only one device to be used, while Windows 7 allows multiple caches, one per device, up to a total of 256 GB. [5]
