It takes dnscache several queries and 25 seconds to return NXDOMAIN.
Unbound responds in 1.5 seconds, including DNSSEC validation and
"harden-referral-path" option.

I think it has to do with dnscache resolving all glue before proceeding
to the next level. The log shows a lot of outgoing queries and several
"input/output errors" as well as "protocol errors".
