Operating System (OS) settings Swappiness Swappiness is a Linux kernel setting that influences the behavior of the Virtual Memory manager when it needs to allocate a swap, ranging from 0-100. Without further ado, let’s start with the OS settings. A setting of 100 determines it to swap aggressively to disk.
