It is recommended that any performance tuning services like tuned be disabled. As root, change the current value in the operating system and by adding a line vm.swappiness = 0 to /etc/sysctl.conf to ensure that the correct setting is applied when the system restarts.
If performance tuning is required, vm.swappiness can be set by cloning the existing performance profile then adding vm.swappiness = 0 to the new profile's tuned.conf file. This file is located at /usr/lib/tuned/profile-name/tuned.conf. The updated profile is then selected by running tuned-adm profile customized_profile.
