How do I stress test CPU and RAM (at the same time)?
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.
