We run our primary resolvers on Raspberry Pis with unbound. I routinely test them against GRC's DNS benchmark test https://www.grc.com/dns/benchmark.htm and they come out significantly faster than any other server out of the entire list. Been using Pi2s for 2+ years now without a single hiccup and just upgraded them to pi3 this week.
Here's some graphs to show how heavily they're used: http://g.vntx.net/a72a8dc4-4804-4fe0-b6d1-1cd279b4070e.png And the cpu usage for the same period: http://g.vntx.net/5e0b9e98-f774-4057-a1d0-2b37c15bde37.png Graham McIntire Verona Networks On Wed, Oct 18, 2017 at 9:35 AM, Matt <[email protected]> wrote: > I would used Centos 7.
