Swap: Why You Need It and How to Enable It

2025-09-03

Swap is virtual memory on disk that saves your VPS from crashing when RAM runs out. On low-cost servers, it’s an indispensable tool to avoid failures during short-term memory usage spikes. Setup is simple: create a file, enable it, and add it to autoload. But remember — it’s insurance, not a replacement for RAM.


Introduction

Modern VPSs are usually provisioned with enough RAM but often without swap (swap file or partition). This is a deliberate choice by providers who want you to quickly upgrade to a more expensive plan.

We needed to find out why the site periodically goes down. Mikhail conducted an audit and found the problem. He's a competent specialist — a pleasure to work with. He approaches tasks responsibly, doesn't disappear or forget )))
