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.

    It shouldn't be surprising. Your ISP's server serves enough customers that most popular sites will be cached most of the time, and you're likely to have a shorter ping time to your ISP's server than to any other.
