                the job to exit. The same format as rate is used for read vs
                write separation.
 
+rate_poisson=bool      When rate limited, try to simulate request flow under
+               Poisson process (instead of even distribution). Default: false.

 latency_target=int     If set, fio will attempt to find the max performance
                point that the given workload will run at while maintaining a
                latency below this target. The values is given in microseconds.
