Abstract
In an embodiment, a target number of discretionary pages for a first partition is calculated as a function of a number of physical page table faults, a number of sampled page faults, a number of shared physical page pool faults, a number of re-page-ins, and a ratio of pages. If the target number of discretionary pages for the first partition is less than a number of the discretionary pages that are allocated to the first partition, a result page is found that is allocated to the first partition and the result page is deallocated from the first partition. If the target number of discretionary pages for the first partition is greater than the number of the discretionary pages that are allocated to the first partition, a free page is allocated to the first partition.
