namebench (Open-source DNS Benchmark Utility)
http://code.google.com/p/namebench/
Are you a power-user with 5 minutes to spare? Do you want a faster internet experience?
Try out namebench. It hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. namebench is completely free and does not modify your system in any way. This project began as a 20% project at Google.
namebench runs on Mac OS X, Windows, and UNIX, and is available with a graphical user interface as well as a command-line interface.
namebench was written using open-source tools and libraries such as Python, Tkinter, PyObjC, dnspython, jinja2 and graphy.

Note: tested with Norton DNS not Comodo ones because Comodo DNS are too slow for me (I’m located in Europe).
It takes more than 5 minutes but more like half an hour or more to complete…
