prepaging
working set model
<architecture> (Or "working set model") A technique whereby
the {operating system} in a {paging} {virtual memory}
{multitasking} environment loads all pages of a process's
{working set} into memory before the process is restarted.
Under {demand paging} a process accesses its working set by
{page faults} every time it is restarted. Under prepaging the
system remembers the pages in each process's working set and
loads them into physical memory before restarting the process.
Prepaging reduces the {page fault} rate of reloaded processes
and hence generally improves CPU efficiency.
