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 ksm_committed Host.ksm_shareable)
(if (and (> (+ ksm_pressure_threshold ksm_committed) Host.mem_available)
(< (Host.StatAvg "mem_free") ksm_pressure_threshold))
Regards
