I had noticed from a month or so back that the cache hit statistics were steadily declining over time [from high seventies where it had stayed consistently before ... to low sixties] – which did not make sense in a small household where the internet usage patterns are fairly consistent.
So - I setup a factory reset router with my usual amtm add-ons – all fresh installed on a formatted USB – and then monitored unbound cache stats with only a SINGLE client PC attached to the router by Ethernet cable. I went about opening the same web pages [30 of them] repeatedly but clearing the DNS cache on the PC between each of the attempts.
After an initial modest pickup in cache hits – I found that repeated opening of the same web pages caused the cache hit stats to DECLINE ??? See images below ...
