Enable KSM

[hashime]

Hello

KSM is disabled by default

cat /sys/kernel/mm/ksm/run
0

Shouldnt that be enabled by default?

Whenever i echo 1 to run, some pages get shared but its reset to 0 in a few seconds.

Is that intended? Whats the proper way to enable it?

Hi,

ksmtuned daemon is enabled by default

(check /etc/default/ksmtuned )


But, it's only running when memory reach 80%. (because it's use cpu)

This can be change here:

/etc/ksmtuned.conf

# KSM_THRES_COEF=20 (80%)

That makes sense, thank you.
