stress-ng #554

Is stress-ng --aggressivve meant to fully put the cpu on max load or is it not, Because I've tried using it and it uses 80% but without it uses 100% what is the full purpose of aggressive |

the aggressive option is intended to exercise the overall system more aggressively as opposed to make a stressor max out the CPU more in userspace. The aggressive option forces more cache/memory and scheduler heavy operations and this will impact on the performance of userspace processes. I suspect in the --cpu stressor case the cpu affinity changes impacts negatively on overall % utilisation stats. |
