It identifies memory pages that have not been accessed recently and moves them to the swap area. The Mechanics of How Swapping Works When the system's physical memory is fully utilized and a process requires additional RAM, the Linux kernel steps in to manage the situation.
Understanding the Swap Mechanism: How Linux Moves Data Between RAM and Disk
A common rule of thumb for systems with large amounts of RAM is to allocate swap space equal to the RAM size, while systems with less RAM might require swap space equal to twice the amount of RAM. To mitigate this, it is best practice to monitor swap usage and ensure that the system has enough physical memory to handle peak loads.
This mechanism acts as a safety net, allowing the system to continue operating under heavy load rather than crashing unexpectedly. This constant swapping of data in and out is handled transparently by the kernel, ensuring that applications remain responsive.

When an application consumes more memory than is available, the kernel may become unresponsive. The first is a dedicated swap partition, which is a separate section of the disk specifically allocated for swapping.
