  • First step: Decrease swap use. This is specially useful fow low RAM (2GB or less) systems. You can check swap use by this command:

    cat /proc/sys/vm/swappiness

    This is generally set to 60. To change the swappiness into a more sensible setting, type in the terminal

    sudo nano /etc/sysctl.d/99-sysctl.conf

    At the end of this file, append the following line.

    This software memorize what applications you use most often and preload related libraries and binaries into memory so these applications can be launched faster.
