Re: [Users] Custom settings for Kernel Same-page Merging (KSM)?

Hi Sven, the reason is that the rule is a bit more complex now. KSM is started when free memory drops below 20% or if the ksm_shareable value gets above 80% of available memory. the relevant rule in the policy is: (defvar ksm_pressure_threshold (* Host.mem_available ksm_free_percent)) (defvar
