V Kompany S Blog Ksm Kernel Samepage Merging To measure the effectiveness of ksm, we made a utility (see attached ksm.txt) that can collect system ksm information (like pages shared, pages sharing, etc) and generate a csv file. Ksm can save memory by merging identical pages, but also can consume additional memory, because it needs to generate a number of rmap items to save each scanned page’s brief rmap information.
V Kompany S Blog Ksm Kernel Samepage Merging The kernel samepage merging (ksm) subsystem works by finding pages in memory with the same contents, then replacing the duplicated copies with a single, shared copy. Description: enable and tune kernel samepage merging (ksm) on ubuntu to reduce memory usage in virtualization environments by deduplicating identical memory pages across virtual machines. Enable and tune kernel samepage merging (ksm) on ubuntu to reduce memory usage in virtualization environments by deduplicating identical memory pages across virtual machines. What is kernel samepage merging (ksm)? kernel samepage merging is a memory de duplicating scheme that finds duplicate anonymous memory pages and shares them in order to alleviate memory bottlenecks.

What is kernel samepage merging (ksm)? kernel samepage merging is a memory de duplicating scheme that finds duplicate anonymous memory pages and shares them in order to alleviate memory bottlenecks. Ksm will simply keep those pages until we don't require and merge with the older addresses. so your tasks for reloading addresses again and again will be reduced. The project consists of developing code to test the performance of the memory saving feature kernel samepage merging (ksm) when using huge pages. these tests are called kselftests, and are contained in the kernel tree. Since the contents of the pages may change at any moment, ksm cannot just insert the pages into a normal sorted tree and expect it to find anything. therefore ksm uses two data structures the stable and the unstable tree. In the kernel summit track at the 2023 linux plumbers conference (lpc), stefan roesch led a session on kernel samepage merging (ksm). he gave an overview of the feature and described some recent changes to ksm.
