Overcoming Observer Effects in Memory Management with DAMON
Knowing the data access pattern of a system and its workloads is crucial for efficient memory management. However, accurate measurement can be challenging due to observer effects.
This talk will introduce how the Linux kernel overcomes this problem using the DAMON subsystem and share practical use cases of it for improving memory efficiencies on real world product Linux systems.
