How to measure cache hit resolution time in unbound 1.24.1

[sir izake]

Hi

I have installed unbound 1.24.1 on FreeBSD 14.3 OS. My cache hit rate is
76% with over 20% coming through recursive replies.

The median time for recursive replies is 440ms while the avg is 520ms.

This setup has been running for over 72hrs. I expect stats to improve but
that is not happening.

Just wanted to find out if there is a way to measure the cache hit
resolution time in a dashboard?

Can I do anything to improve cache hit ratio?

Can I also improve the recursive reply time?

I am using unbound_exporter to monitor stats in grafana

My configs have been adjusted as follows:
rrset-cache-size: 20G
msg-cache-size: 10G
cache-min-ttl: 1800

I am using the root hint files directly on the server for recursive lookup
and not forwarding to any public resolver

Thank you

Regards,
Isaac
