# Make the Swap File Permanent

# Update swappiness
# For a Desktop, a swappiness setting of 60 is not a bad value. For a server, you might want to move it closer to 0.
sudo sysctl vm.swappiness=10
sudo echo vm.swappiness=10 >> /etc/sysctl.conf

# Adjusting the Cache Pressure Setting
sudo sysctl vm.vfs_cache_pressure=50
sudo echo vm.vfs_cache_pressure=50 >> /etc/sysctl.conf
