Raff Sustained CPU Endurance Run
CPU-Opt 4 vCPUs 8 GB - Jun 27 2026

Go to Raff



The sustained CPU endurance test runs a cpu intensive task in a loop for 24 hours. As maxing out the cpu might be considered abusive, the tests aims to use no more than 50% of each cpu core on the VPS.

The purpose of this type of test is

  • first to evaluate the speed to the VPS,
  • second to evaluate the stability over time of the cpu available to the VPS
  • and third to detect VPS where the CPU is throttled and the performance goes down over time after cpu utilization goes over a threshold the provider considers excessive for a particular plan.

The performance is measured at regular intervals in terms of tasks executed per hour, amount of idle cpu and amount of "cpu steal".
