+rate_poisson=bool	Real world random request flow follows Poisson process

+		rate_poisson=1, fio tries to simulate request flow under Poisson

 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.
