I like the KSM feature myself. Useful when one has more than one
virtual machine on a single server. It automatically recognises
identical pages between two VM and maps them both to a single page,
thus saving a lot of RAM.
Note: KSM is somewhat buggy at the moment, for example, it cause
cryptsetup to fail to mount a crypted fs.

Kind Regards
