A method for pre-fetching of pages prior to a hard page fault sequence is described. A scenario file comprising a list of pages that need to be pre-fetched may be created. A scenario that requires pre-fetching may be automatically detected when process creation begins (such as at application startup or system boot). The scenario begins and it is determined whether or not a scenario file exists for the scenario. If not, the process continues (for example, the application is started up and run, the system is booted, etc.). If a scenario file does exist, the pages in the scenario file are pre-fetched to RAM. The process continues (application is started up and run, the system is booted, etc.). Pages that are used by the application are logged into a scenario log. The scenario log is also used to log page faults. An end scenario timer is started and it is determined whether a page fault (soft or hard) has been detected. Page faults are logged into memory (the scenario log) and the end scenario timer is reset each time a new page fault is encountered. If the end scenario timer has reached a predetermined threshold, the scenario ends and a work item is queued to post-process the scenario log and scenario file during idle time. The scenario file and scenario log are processed and an updated scenario file is written out to the disk space.
