Spot on, I think if the author spent 30min watching an introductory queuing theory video they'd realize that there's so many factors:

* Workload distribution (heavy tailed, exponential, uniform etc.)

* Scheduling policies (FirstComeFirstServe, ShortestRemainingProcessingTime etc.)

* Arrival rate of the jobs (poisson, uniform etc.) in comparison to their "service" rate
