Swap memory setup:

• swapon -s

• free -m

• df -h

• sudo swapon --show

• sudo fallocate -l 8G /swapfile

• ako ne radi fallocate => sudo dd if=/dev/zero of=/swapfile count=4096 bs=1MiB

• ls -lh /swapfile

• sudo chmod 600 /swapfile

• sudo mkswap /swapfile

• sudo swapon /swapfile

• swapon -s

• free -m

• df -h

make swap permanent:

• sudo nano /etc/fstab => /swapfile swap swap sw 0 0

performance tweak:

• cat /proc/sys/vm/swappiness

• sudo sysctl vm.swappiness=10

• sudo nano /etc/sysctl.conf => vm.swappiness = 10

• cat /proc/sys/vm/vfs_cache_pressure

• sudo sysctl vm.vfs_cache_pressure=50

• sudo nano /etc/sysctl.conf => vm.vfs_cache_pressure = 50
