Hello, rec-control is a command from the recursor, so why are you talking about your authoritative nameserver? There are a too small number of queries - you can not draw conclusions from this, in my opinion.
Here’s an example from my ns: root@ns1:~# rec_control get-all|grep cache cache-entries 119504 cache-hits 474284 cache-misses 10249358 max-cache-entries 1000000 max-packetcache-entries 500000 negcache-entries 11014 packetcache-entries 82704 packetcache-hits 17015067 packetcache-misses 10715597 best regards, Markus Von: Pdns-users <pdns-users-boun...@mailman.powerdns.com> Im Auftrag von ???

How can I optimize it?
