Kernel same-page merging

Index Kernel same-page merging

In computing, kernel same-page merging (abbreviated as KSM, and also known as kernel shared memory and memory merging) is a kernel feature that makes it possible for a hypervisor system to share identical memory pages amongst different processes or virtualized guests. [1]

Copy-on-write

Copy-on-write (CoW or COW), sometimes referred to as implicit sharing or shadowing, is a resource-management technique used in computer programming to efficiently implement a "duplicate" or "copy" operation on modifiable resources.
