Memory deduplication is a popular technique to reduce the memory footprint of a running system by merging memory pages with the same contents. Until recently, its primary use was in virtualization solutions, allowing providers to host more virtual machines with the same amount of physical memory [32], [34], [7]. The last five years, however, have witnessed an increasingly widespread use of memory deduplication, with Windows 8.1 (and later versions) adopting it as a default feature inside the operating system itself [6].
