Abstract: An efficient, on-demand, content-based memory sharing method is performed by a system. The method begins when an event is detected. The system predicts a merge gain based on a current number of candidate pages in the memory, a current number of merged pages, and a merge ratio which represents a merged-to-candidate page ratio. In response to a determination that the merge gain is greater than a threshold, the system performs a scan and merge operation to merge a set of the candidate pages, which have a same content and have not been merged, into a single page having the same content.
