1. Check if you haven’t got swap. I didn’t by default it seems it does not get created.
# free – This will display available memory
# fallocate -l 1G /mnt/1GB.swap
# mkswap /mnt/1GB.swap
# swapon /mnt/1GB.swap
and add the records to your /etc/fstab
# echo “/mnt/1GB.swap none swap sw 0 0” >> /etc/fstab
Now display your swappines value
# cat /proc/sys/vm/swappiness
normally it’s 60 ( This means that Kernel is more likely to put things into Swap than memory)
Swappiness it is just a value it does not mean that were you memory will be able at 60% it will start putting things to swap.
You may find it useful although 10 should be fine you can always tune it later if needed.
The swap tendency can have a value of 0 (fully off) to 100 (swap is constantly used).
sudo sysctl vm.swappiness=10
then add it to your
and for the god sake of LOL reboot yourserver
#shutdown -R now
A workable and practical rule for changing the swappiness can be:
1 GB or more RAM: 10
Less than 1 GB of RAM: 1
