If you have a fast CPU and/or don’t want swap eating up your storage, zRAM is for you.

zRAM dedicates a portion of your RAM to act as a swap space, but compressed to save RAM.
This is faster than traditional swap on HDD and SSD as it uses the speed of the RAM.

To enable zRAM in Linux Mint, type this on the terminal:

1
2

sudo apt update
sudo apt install zram-config

And reboot your system, zRAM is now configured in your Linux Mint.

To disable swapfile since you already have zRAM, type this on the terminal:

1
2
3
4

sudo swapoff /swapfile
sudo rm /swapfile
sudo cp /etc/fstab /etc/fstab.bak
sudo sed -i '/\/swapfile/d' /etc/fstab
