Low cache hits with unbound in Resolver mode

Hi,
Since the installation of 20.7, I'm seeing a low cache hit in Unbound.
Now it's running at 8%. Before, it was normally around 80% of cache hits.
The settings are identical of what I used to have (I've installed 20.7 from the scratch).
Are anyone seeing similar results ? Any idea on how to improve it ?

What’s the uptime of unbound? Perhaps it gets restarted periodically (after DNSBL updates) or upon network events? This could explain a low hit rate.

In theory there is no difference between theory and practice. In practice there is.

Percentage of cache hit should increase as uptime of the service increases. Since it's freshly updated I wouldn't expect a high hit rate until it's been up for some time and built up a larger cache size. Same after service restarts or system reboots.
