Use a part of your RAM as compressed swap.
zram is a Linux kernel feature
that provides a form of virtual memory compression. zram module increases
performance by avoiding paging to disk and using a compressed block device in
RAM instead, inside which paging takes place until it is necessary to use the
swap space on a hard disk drive. Since using zram is an alternative way to
provide swapping on RAM, zram allows Linux to make a better use of RAM when
swapping/paging is required, especially on older computers with less RAM
installed.
This program provides a systemd service to automatically load and configure such module at system boot.
You can choose compression algorithm by editing systemd service. To see available
algorithms do cat /sys/block/zram0/comp_algorithm.
You can choose between different installation methods. Note that uninstallation don't removes active zram disk.
