I see great differences in the top 5 fastest dns-servers on my Macbook, when running the script a couple of times with like a few minutes in between; Sometimes cloudflare is fastest, sometimes cloudflare is very slow, etc.

So the results everyone posts here are pretty useless i believe (since it's just a single test.)

When using WPT to benchmark network latency from a given location, a rule of thumb I adopted during my years as a webperf engineer was to repeat the test 9x. Using an odd number ensured the median run was an actual test, and 9 seemed sufficient to iron out the inevitable temporal inconsistencies, while allowing the overall test suite to finish in a reasonable time. The fastest value was sometimes more interesting / useful than the median though.
