Dear Steinar,

I'm using PowerDNS Authoritative only. I don't active recursor on my server.
Because when I test query and monitor with htop. I didn't see my RAM
increase so I think PDNS store cache in HDD. Will recursor.conf effect in
PowerDNS Authoritative ? I want to store query results from VPS Database on
VPS PowerDNS's cache.

Thanks & Best Regards,
