      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.
