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".
Number of tasks completed per hour
| Date | Number of iterations per hour | CPU Idle % | CPU Steal % |
