How to configure the Tuning HYDRA-GTK ?

Someone already used once HYDRA-GTK, GUI THC-Hydra? If so, I would like to know how to set Tuning that contains the Number of Task Timeout and at the bottom when we want to use it with a large dictionary of its kind RockYou.txt ?

1 - How much should I put as the "Number of Task" as the RockYou.txt dictionary (139.92 MB) contains millions of passwords ?

2 - How much should I put as the "Timeout" since the RockYou.txt dictionary (139.92 MB) contains millions of passwords ?

Thank you to inform me please.
