[root at ops-dns-recursor-1 ~]# rec_control get-all |grep cache
Is this a recursive node that has been running for a while, and the probability of a cache hit and a packet cache hit seems normal? Why do I feel a little less?

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 at ns1:~# rec_control get-all|grep cache
Von: Pdns-users <pdns-users-bounces at mailman.powerdns.com> Im Auftrag von ???

I don't know if the data monitored on my authoritative node is normal, but it seems that there is a high probability that the miss will be lost. How can I optimize it?
