Check out Hans' "Anatomy of the command line" talk that he gave at SCaLE. It will show you in detail why that didn't work.... you'll learn a lot. It's at: https://www.youtube.com/watch?v=Yx_dCte3dEE As for setting the swappiness permanently create and edit /etc/sysctl.d/10-swappiness.conf, it probably won't exist by default. Then put a single like it that is: vm.swappiness=10 If you want your swappiness set to 0, just change the 10 to 0 Brian Cluff On 03/01/2016 06:26 AM, Michael wrote: > I understand.
