• Stress virtual memory with 2 workers for 30 seconds:

stress-ng {{[-m|--vm]}} 2 --vm-bytes {{512M}} {{[-t|--timeout]}} 30s

• Stress the I/O subsystem with 3 workers for 45 seconds:

stress-ng {{[-i|--io]}} 3 {{[-t|--timeout]}} 45s

• Run all stress tests for 2 minutes:

stress-ng {{[-a|--all]}} {{1}} {{[-t|--timeout]}} 2m
