== How to check efficiency of KSM ==

To check if KSM is actually reducing memory usage, issue this command on the HN:

[root@HN /]# cat /sys/kernel/mm/~~KSM~~ksm/pages_sharing

If the value is greater than 0, you're saving memory. Refer to https://www.kernel.org/doc/Documentation/vm/ksm.txt for more details.
