  • Spawn 4 workers to stress test CPU:
    stress -c 4
  • Spawn 2 workers to stress test IO and timeout after 5 seconds:
    stress -i 2 -t 5
  • Spawn 2 workers to stress test memory (each worker allocates 256M bytes):
    stress -m 2 --vm-bytes 256M
  • Spawn 2 workers spinning on write()/unlink() (each worker writes 1G bytes):
    stress -d 2 --hdd-bytes 1GB
