Swap uses some of your SSD as (very slow) RAM.

```plaintext
      install -o root -g root -m 0600 /dev/null /swapfile
      fallocate -l 2G /swapfile
      mkswap /swapfile
      swapon /swapfile
      echo "/swapfile swap swap auto 0 0" | tee -a /etc/fstab
      sysctl -w vm.swappiness=10
      echo 'vm.swappiness = 10' > /etc/sysctl.d/30-discourse-swap.conf

```
