摘要
A method for reducing reactivation time of services that includes examining page faults that occur during processing of a service after the service has been inactive to provide a plurality of prefetch groups, and formulating a prefetch decision tree from page fault data in the prefetch groups. Pages from an initial page table for the service following a reactivated service request are then compared with the prefetched pages in the resident memory in accordance with the prefetch decision tree. Pages in the page table that are not included in said prefetched pages are paged in. A process to provide to provide the service is executed using the page table. Executing the process substantially avoids page faults.
