number of forward-zones vs. performance

[Yorgos Thessalonikefs]

Hi Andreas,

I don't expect so but I am also not an operator of that many forward 
zones :)
For sure you would need more memory.

I guess you would also need to manage/change said forwarding 
configuration and from Unbound 1.23.0, you can use
     unbound-control fast-reload
to pick up any changes from the configuration file(s) and apply them 
without service interaction.
You can read more about it in the unbound-control manpage also online [1].

Best regards,
-- Yorgos
