[Pdns-users] How to optimize cache hit ratio

[姜伯洋]

Hello everyone
[root at ops-dns-recursor-3 ~]# rec_control get-all|grep cache
cache-entries121
cache-hits0
cache-misses12
max-cache-entries3000000
max-packetcache-entries500000
negcache-entries4
packetcache-entries7
packetcache-hits51
packetcache-misses12
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?
