About KSM
What is Kernel Same-page Merging?
KSM is a memory-saving de-duplication feature that scans memory looking for pages with identical content. When identical pages are found, they are merged into a single page, with copy-on-write semantics.
Best For
- Virtual machines running similar operating systems
- Container environments with shared base images
- Systems with many similar processes
Configuration Tips
- Pages to Scan: Higher values = faster merging but more CPU usage
- Sleep Time: Lower values = more aggressive scanning but higher CPU usage
- Default values (100 pages, 20ms) provide a good balance
