Learn more about Linux swap and improve your system performance

In the Linux operating system, swap is a very important concept. It can provide additional memory space for the system and improve the performance and stability of the system. However, for many novices, swap may still be a relatively unfamiliar concept and they do not know how to configure and manage it. In this article, we will have an in-depth understanding of Linux swap, so that you can better configure and manage the system's swap space and improve the performance and stability of the system.

If you finally decide to switch from Windows to Linux. About halfway through the installation process, you will see the term "Linux Swap" and if you want to know what it is, then check out this article. Let’s see what swap space is in Linux and whether it is essential.

What is Swap in Linux?

Swap is similar to the memory expansion feature on smartphones that some manufacturers have recently offered. In short, it uses the phone's internal storage (like RAM) if there's not enough actual RAM space. Likewise, on Linux, swap space prevents your computer from crashing if your physical RAM is full by storing volatile data on its internal storage (HDD/SSD).

Creating swap space is not necessary for installing Linux, but if your computer has less RAM and more storage space, you can save some to make some swap space, as it is in some cases Might come in handy.

How much space is created for swap?

So, if your computer has the features we mentioned above, creating swap space is not bad, but the question is, how much should you create?

There is of course no limit to how much swap you can create, but common wisdom is "half the memory size". However, only create swap if you're sure you'll be running memory-intensive programs and doing a lot of multitasking, otherwise you'll actually be wasting storage space that you could be using to store other things.

How to create swap in Linux?

Considering that you are already in the installer and have created the / and /home partitions, the next step will be to create swap space. All you need to do is create an empty partition of a size that depends on how much RAM you have (if you have 8GB of RAM, you'll need at least 2GB to 4GB of swap space). In the options, select "Use this as exchange" or any exchange-related word and click Create. You can then proceed with the installation process.
