Kernel Same-page Merging

From DALL-E with some prompting
Kernel Same-page Merging (KSM) is a feature within an operating system’s kernel that enhances memory efficiency by identifying and merging identical memory pages. Typically, this process is beneficial for duplicated pages from executable files and shared libraries, which are common across different processes. KSM is also advantageous in environments where there is a significant amount of shared data and memory-mapped files, such as virtualization systems where multiple virtual machines may be running the same operating system or similar applications. By merging these pages, KSM allows for a reduction in physical memory usage, leading to better memory management and potentially improved performance for the system.
