Google DNS Benchmarked

“Methodology
Firstly I found a list of the 1 million most popular sites. I then
picked a number of DNS servers to test against. I chose Google’s,
OpenDNS’s, my ISP (Sky/Easynet) and my old ISP’s (Plus.net).

“I decided I would query an A record for each of the domains in
the list, one at a time, starting with the most popular. I would
query each server three times for the same domain name. The
ordering was like this:

foreach (domain)
   for (i =0; i<3;i++)
      foreach (server)
         query(server, domain)
