I ask, in what world do you have "slow DNS"? The choices out there is ISP run which virtually always low latency, an anycast run service, or running your own.
I don't care what technology you throw at the problem or who designed it, there really isn't "slow DNS", just bad choices of DNS servers that incur a round-trip latency penalty. I will assert again what keeps DNS "fast" is the aggressive caching of responses.
