How Linux KSM Is Saving Memory in Virtualized Environments


Listen Later

In this episode of The Linux Podcast with Fexingo, Lucas and Luna dive into Kernel Same-page Merging (KSM), a memory-saving feature that deduplicates identical pages across virtual machines. They explore how KSM works, its performance trade-offs, and real-world use cases like large-scale cloud deployments and embedded systems. With specific numbers—like how KSM can reduce memory usage by up to 90% in some workloads—they explain why this often-overlooked kernel feature is a game-changer for virtualization economics. They also discuss tuning parameters, security implications, and how KSM compares to newer alternatives like KVM's native page merging. A practical look at a technology that quietly keeps cloud costs under control.
