Benefit of it is somewhat questionable, though, unless you have a big system. In reality, zram for swap will give you most of the benefit. The big thing is going to be 0-filled pages, and as they are likely to never be accessed, they'll get swapped out first, and zram will just throw them away. -- You received this question notification because you are a member of AC100 Team, which is an answer contact for AC100_enablement. _______________________________________________ Mailing list: https://launchpad.net/~ac100 Post to : [email protected] Unsubscribe : https://launchpad.net/~ac100 More help : https://help.launchpad.net/ListHelp
