🔧 How to Simulate High CPU Usage on AWS Ubuntu Instances for Testing and Performance Optimization

To increase CPU usage for testing in an AWS Ubuntu instance, we can generate artificial load on the CPU using tools like stress, stress-ng, or custom scripts. Here's how you can achieve this:

1. Using stress

stress is a simple workload generator for Linux systems.

Install stress:

sudo apt update
sudo apt install stress

Generate CPU Load:

Run the following command to create CPU stress:

stress --cpu 4 --timeout 60
  • --cpu 4: Number of CPU cores to stress (adjust based on your instance's available cores).
  • --timeout 60: Duration in seconds for the stress test.

2. Using stress-ng

stress-ng is more advanced and flexible than stress.

Install stress-ng:

sudo apt update
sudo apt install stress-ng

Generate CPU Load:

Run this command to stress all CPUs:

stress-ng --cpu 4 --cpu-load 80 --timeout 60s
  • --cpu 4: Number of CPU stressors to run (one per core).
  • --cpu-load 80: Set each CPU to run at 80% utilization.
  • --timeout 60s: Run for 60 seconds.

3. Using a Custom Script

You can also use a simple shell script to load the CPU.

Bash Script:

#!/bin/bash
while :; do :; done

Run the Script:

Save the script as cpu_load.sh and execute it:

chmod +x cpu_load.sh
./cpu_load.sh &

This will create a full load on a single core. To create additional load, run multiple instances of the script in the background.

4. Using yes Command

You can use the yes command to generate CPU load.

Run the Command:

yes > /dev/null &

Run this multiple times to stress more cores. Stop the process using kill or pkill yes.

5. Monitoring CPU Usage

To monitor CPU usage during the test, use:

top

or

htop

(Install htop with sudo apt install htop).

6. Clean Up

After testing, terminate the stress processes:

  • For stress or stress-ng, they stop automatically after the timeout.
  • For background scripts or yes, stop them manually:
killall stress
killall stress-ng
killall yes
pkill -f cpu_load.sh
