I ran this against my ISP's DNS as cached by my router, Google's new 8.8.8.8, Level3's 4.2.2.1 and 4.2.2.2, and OpenDNS.

It performed 200 tests in 1 run, using my 100,000 Firefox bookmarks as its data source in 'weighted' mode.

My results were as follows: "In this test, Your current primary DNS server [my router's cache of Comcast's DNS] is 29% Faster than Google Public DNS".

I am in Boston. In ranked order of performance: My router's cache of Comcast (48.28ms), Google's 8.8.8.8 (62.49ms), OpenDNS (68.14ms), Level3's 4.2.2.1 (94.37ms), Level3's 4.2.2.2 (113.51ms)

*Update - I clarified that I tested my router's cache of Comcast's DNS, not Comcast's DNS servers themselves.

200 tests, 1 run. ~33K Firefox items. Weighted.

I was surprised to find my ISP (Cox, San Diego) performed pretty favorably.

Cox (92.73 ms), UltraDNS (100.95 ms), OpenDNS (117.07 ms), Google Public DNS (197.01 ms)

I was also surprised to see that my IPS's DNS servers performed so well against all other services.

Slightly off-topic but when I first got my MacBook about two years ago the networking was awfully slow compared to my Windows or Linux boxes.

I suspected a DNS problem and after installing a local DNS cache server it improved dramatically, so a local cache-only/forwarder DNS server is another solution for a faster networking experience.

Cool that it considers automatic domain redirection an error:

www.google.com. hijacked (google.navigation.opendns.com.) NXDOMAIN Hijacking

I'm getting very different results when I run these tests. At prime time 7 pm to 9 pm pacific time on weekdays is different than sundays at noon.
