Fix Geekbench test failed and low memory was detected.

I ran yet-another-bench-script (yabs) script with my new VPS and encountered an error.

Example yabs result:

Geekbench test failed and low memory was detected. Add at least 1GB of SWAP or use GB4 instead (higher compatibility with low memory systems).

How to fix

As we can see on my benchmark result, my ubuntu template didn't come with a swap (0.0 KiB). So to fix this error, add at least 1 GB of swap. Add swap with this method:

First, create a file that will be used as a swap:

sudo fallocate -l 2G /swapfile

Set the file permissions to 600 to prevent regular users to write and read the file:

sudo chmod 600 /swapfile

Create a Linux swap area on the file:

sudo mkswap /swapfile

Setting up swapspace version 1, size = 2 GiB (2147479552 bytes)
no label, UUID=fde7d2c8-06ea-400a-9027-fd731d8ab4c8

Activate the swap file by running the following command:

sudo swapon /swapfile

Verify that the swap is active by using either the swapon or the freecommand, as shown below:

sudo swapon --show

Output
root@us:~# sudo swapon --show
NAME      TYPE SIZE USED PRIO
/swapfile file   2G  44M   -2

As we can see, I added a 2GB Swap while my ram is 1GB.

However, if we reboot, the server will not retain the swap settings automatically. To make it permanent, add the swap file to our /etc/fstab file.

Back up the /etc/fstab file in case anything goes wrong:

sudo cp /etc/fstab /etc/fstab.bak

Add the swap file information to the end of your /etc/fstab file by typing:

/swapfile swap swap defaults 0 0

/etc/fstab

Re-run yabs script

Ran yabs script to benchmark again with:

curl -sL yabs.sh | bash
