Memory Swap Test Script for Linux

This script tests how memory swapping works between RAM and swap space on a Linux system. It attempts to allocate memory beyond the system's physical RAM, forcing the use of swap space. Here's how it works:

Features

• Memory Allocation: The script allocates memory in chunks, increasing until it either fills up available memory or hits system limits.
• System Load Check: To prevent system lockup or excessive slowdown, the script checks the system load before allocating more memory. If the load is too high, it stops allocating.

How It Works

1. Check Total Memory: It first determines the total physical RAM available.
2. Allocate Memory: It then tries to allocate 1.5 times the total memory in small chunks, printing updates on memory and swap usage.
3. System Load Monitoring: If the system load exceeds a predefined threshold (85% of CPU capacity by default), memory allocation stops to avoid overwhelming the system.

Running the Script

Prerequisites

• Python 3 installed on your system.

• psutil library. Install with:

  pip install psutil
