As anyone used DNS Bench before?

I'm just looking at a utility online called DNS Bench available here: https://www.grc.com/dns/benchmark.htm

As anyone used it before? Is it any good?

Yes works well - does what it says on the tin.

Yes although sometimes it can recommend servers in a snapshot, over time you might have to change to get a quicker server.

In reply to a post by Banger:

Yes good point. When I said "does what it says on the tin", I should probably say "use it for what it is good at", in other words, for benchmarking DNS servers, that does NOT translate to "go and blindly switch your DNS settings just based on what the benchmark" says.

Just bye the bye, on my laptop Malwarebytes blocks access to lots of the servers that DNSBench tries to access while it runs tests.
