Google Public DNS - Performance Comparison

Regardless of the obvious privacy issues, such as letting All Knowing Google to access a big chunk of information about my surfing habits, I still wanted to test out the performance of Google’s DNS service.

In this test I used DNS Performance Test tool provided by Silverwolf. It makes a number of DNS queries to a seemingly random list of domains using your OS’ default DNS settings. I ran the software until 1000 successful queries were made for each DNS provider.

DNS providers in this test were my Finnish ISP Sonera, OpenDNS and of course Google Public DNS.

And here are the results:

So Google Public DNS is indeed fast and even surprisingly fast when compared to OpenDNS.
