How long does the calculation of dynamic roles take?

Hello Community,

we are using One Identity Manager version 8.1.5

We have a schedule to which about 100 dynamic roles are currently assigned. A request came up to create more dynamic roles that we would need to assign to this schedule.
The question we have is how long does it take to calculate these roles? Is the frequency of 1 hour still sufficient or is it now already critical?
Is there a procedure to determine the calculation time?

Thanks for any hints or ideas
