If dig doesn't show a delay, then it is NOT the DNS itself that is
causing the delay, but the querier (browser, whatever).

BTW those two queries were for different names, so not a useful
comparison.

You could also bypass dnsmasq by doing this:

   dig esprimo.zbmc.eu @ip-address-of-nameserver

... but from the sound of it there will be no difference anyway.

What are you doing that causes the lookups? A browser, something else?
