Abstract
Techniques described enable efficient swapping of memory pages to and from a working set of pages for a process through the use of large writes and reads of pages to and from sequentially ordered locations in secondary storage. When writing pages from a working set of a process into secondary storage, the pages may be written into reserved, contiguous locations in a dedicated swap file according to a virtual address order or other order. Such writing into sequentially ordered locations enables reading in of clusters of pages in large, sequential blocks of memory, providing for more efficient read operations to return pages to physical memory.
