Adjusting the Swappiness Property

This is a value between 0 and 100 that represents a percentage

0 = not use swap, 100 = keep more RAM

cat /proc/sys/vm/swappiness

60  //output

sudo sysctl vm.swappiness=10 //reboot reset

OR 

vim /etc/sysctl.conf
vm.swappiness=10

Adjusting the Cache Pressure Setting

This setting configures how much the system will choose to cache inode and dentry information over other data.

sudo sysctl vm.vfs_cache_pressure=50 //reboot reset

OR

vim /etc/sysctl.conf
