Of course it is not used to share data among different
customers/tenants, as far as I know it is used by Oracle Cloud to
merge the same pages in clear containers.

One performance enhancing feature is the use of KSM, a recent KVM
optimized for memory sharing and boot speed. Another is the use of an
optimized Clear Containers mini-OS.
