ABSTRACT:
The illustrative embodiments described herein provide a computer implemented method, apparatus, and computer program product for adjusting a page size for a virtual memory range. The process identifies a set of pages in the virtual memory range that reside on a primary memory to form a page occupancy. Each of the set of pages has a first page size. The process changes the first page size to a second page size in response to a comparison of the page occupancy to a threshold value indicating that the first page size should be adjusted.
