DNS Resolver with DNS forwarding x2 slower than DNS Forwarder
pfsense 2.4.5-RELEASE-p1 (amd64)
So I had pfsense DNS Resolver configured with forwarding enable to upstream DNS servers but had been noticing slow page loads. So switched over to DNS Forwarder with significant improvements.
I used namebench to test against the top 2000 sites (alexa)
Resolver 50% of queries under 110ms
Forwarder 50% of queries under 30ms
Overall average fell ~130ms
While I understand the Unbound resolver would be slower even with forwarding enable the performance gap here is more significant than I would expect. It could be something specific to my resolver config, which I've included at the bottom

When forwarding - using the resolver Unbound or dnsmasq (the other DNS forwarder) you could - should for timing issues ? - de activated DNSSEC.
As DNSSEC makes no sense when forwarding.
When you are forwarding, you might as well stop using unbound - the Resolver, and go for dnsmasq (the Forwarder).
Following. We are looking for solutions as well. We are having issues with DNS in https://www.yarno.dk

Like no SOA. That's bad.
DNS forwarding, Resolving, whatever, if your DNS zone is bad things become messy.
edit : correction :
There it is :
dig yar??.dk SOA +short
logan.ns.cloudflare.com. dns.cloudflare.com. 2034779557 10000 2400 604800 3600
No DNSSEC neither ? I thought that in the north things were done seriously these days ;)
