increase SWAP size in Raspberry Pi

What is SWAP memory?

SWAP memory is basically parts of memory from the RAM (Random Access Memory) that enables an operating system to provide more memory to a running application or process than is available in physical random access memory (RAM). So if the physical memory (RAM) is full, we can use SWAP partition for extra memory resources. It is useful if we have low memory on our machine.

Step 1: Stop the SWAP

sudo dphys-swapfile swapoff

Step 2: Modify the SWAP size

As root, edit the file /etc/dphys-swapfile and modify the variable CONF_SWAPSIZE:

sudo nano /etc/dphys-swapfile

Edit the line and enter decide swap size in MB CONF_SWAPSIZE=1024

and save ^ + x

Step 3: Create and initialize the file

Run

sudo dphys-swapfile setup

Step 4: Start the SWAP

sudo dphys-swapfile swapon
