I've searched the net and came across the Ubuntu wiki saying

stress-ng --matrix 0

is supposed the best. But there are dedicated stressors for CPU and RAM (looking at man).

Any ideas which one is the best to use? Thank you

You can install stress with:

sudo apt install stress

Then call it with:

stress --cpu 8 --io 4 --vm 4 --vm-bytes 1024M --timeout 10s

On my conky display notice how:

  • In the top section CPU utilization spikes from 3% to 100%
  • In the middle the temperature spikes from 60C to 80C
  • At the bottom memory spikes from normal 2.75 GiB to 6.25 GiB

Type stress --help for a full list of options.


A commentator requested posting the entire conky script which I did here: conky transparent

    @mrjayviper It is called conky it's a light weight system monitor that is highly configurable and very popular in Linux world. You can google conky for more information. You can also search here in Ask Ubuntu and in Ubuntu Forums. – WinEunuuchs2Unix Aug 23 '17 at 3:58

    @mrjayviper Had to search a bit to find the old post but here it is: Ubuntu Forums share your .conkyrc There are many other .conkyrc themes in the forum better than my own. – WinEunuuchs2Unix Aug 23 '17 at 10:13

    It might be worth mentioning that in order to install stress and /or conky as outlined in your answer and comments you must first enable the universe repository – Elder Geek Sep 21 '17 at 15:21
