I've got BIND9 DNS running on local Ubuntu machine. Used https://help.ubuntu.com/lts/serverguide/dns-configuration.html to set it up.

Everything works ok, but sometimes it take awhile to load, especially the first visit.

DNS Lookup

Is there anyway I can troubleshoot to find the the cause for such slow lookup? Could it be configuration settings?

Any help would be greatly appreciated, thanks

Are all your problems related to your miss-use of the .local domain? Are you sure your system isn't attempting Multicast DNS resolution and timing out?

If this is the problem, you need to disable avahi/bonjour lookups on your systems.

If you set up a local name server then nothing is cached until you visit it. A local name server will look everything up via the root name servers and then follow all the referrals to get the answer. Hosting your own DNS is a good thing, but whatever you make the DNS server, you have to keep it running all the time.
