sorry, didn't realize I had not sent it to the list too.
I have ran the command again several times, and now it is much slower, ~30/40 msec

Pretty slow my dig to the same server ran in 113 msec
yes, >2 seconds seemed high to me too. But what does this mean? What can the reason be?
Thx Marco

Innocent, ignorant, curious ramble:
I understand it has something to do with MX records...
Dunno if it will help.. Will setting DNS to 8.8.8.8 help?
or will it require payment to google?
Recently in India, there were issues with DNS.

No that doesn't require payment. Usually you want you DNS to be close to keep the response time short but with a 2 second response time pretty much any nameserver in the world will be faster. So go ahead and use 8.8.8.8 and see if that works better.

It could be your VM's problem if every operation is slow. 1 gig isn't much RAM these days and that is the obvious thing to fix. If the DNS server is responding quickly to others (I see about 200msec in the US), then it probably isn't the root cause of your problem.
