Always think out of the box. Do not restrict yourself to just Arch Linux articles or ArcoLinux articles.
We use an article for Ubuntu to increase the swap file.
Turn off all swap processes
sudo swapoff -a
Resize the swap (from 512 MB to 8GB)
sudo dd if=/dev/zero of=/swapfile bs=1G count=8
if = input file
of = output file
bs = block size
count = multiplier of blocks
Make the file usable as swap
sudo mkswap /swapfile
Activate the swap file
sudo swapon /swapfile
Check the amount of swap available
grep SwapTotal /proc/meminfo
Or use applications such as htop, gtop, glances and others.
