Our instructions say: `echo "/swapfile swap swap auto 0 0" | tee -a /etc/fstab sysctl -w vm.swappiness=10` note `swappiness = 10` there > **[Memory paging](https://en.wikipedia.org/wiki/Swappiness)** > > In computer operating systems, memory paging is a memory management scheme that allows the physical memory used by a program to be non-contiguous. This also helps avoid the problem of memory fragmentation and requiring compaction to reduce fragmentation. > Paging is often combined with the related technique of allocating and freeing page frames and storing pages on and retrieving them from secondary storage\[a\] in order to allow the aggregate size of the address spaces to exceed the physical mem...
