Speed up your system by avoiding the swap file

Check system swappiness value by running: cat /proc/sys/vm/swappiness #100 means that programs will be swapped to disk almost instantly #0 means that the disk will be avoided unless absolutely necessary To change the system swappiness value, vi /etc/sysctl.conf vm.swappiness = 15 # The swap file will then only be used when my RAM usage is around 85% Then reboot for the change to take effect. Change the value while your system is still running: sysctl vm.swappiness=15
