Abstract
Systems, methods, and articles of manufacture comprising processor-readable storage media are provided for managing memory by persistence of page access heuristics. For example, a method includes collecting, during run-time execution of an application, access heuristics with regard to each page of data that is accessed by the application and cached in a page cache associated with the application, and generating metadata for each cached page in the page cache. The metadata for a given cached page represents the access heuristics of the given cached page. The metadata for each cached page is maintained in a volatile memory during run-time execution of the application. Moreover, the metadata for each cached page is persistently stored in a non-volatile memory during run-time execution of the application. The persistently stored metadata for each cached page is accessed when the application is restarted to restore the page cache associated with the application to a previous state.
