### SETUP SWAP FILE
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
#Double check it was created:
sudo swapon -s
#Or
free -m
#To make it run after reboot:
#sudo nano /etc/fstab
sudo sh -c "echo '/swapfile none swap sw 0 0' >> /etc/fstab"
#To check swapiness percentage:
cat /proc/sys/vm/swappiness
#It will be probably 60, it’s better to decrease to 10
sudo sysctl vm.swappiness=10
#To make it permanent:
#sudo nano /etc/sysctl.conf
sudo sh -c "echo 'vm.swappiness=10' >> /etc/sysctl.conf"
