Would you consider sending metrics to our public metronome server  so we understand what's the limiting factor during your tests? You only need to add a line like this one to your dnsdist configuration: carbonServer("22.214.171.124:2003", "put-the-name-you-want-to-display-here", 5) This will only send some metrics without any private information and is very useful to understand where the bottleneck may be. : https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open/ : https://metronome1.powerdns.com/ Best regards, Remi > On Thu, 8 Aug 2019 at 10:52, Remi Gacogne <remi.gaco...@powerdns.com > <mailto:remi.gaco...@powerdns.com>> wrote: > > Hi Gentian, > > On 8/8/19 10:20 AM, Gentian Bajraktari wrote: > > but when we test with resperf (from dnsperf tool), the results are > very > > bad for DNSDIST, around 5-15K QPS , while when we test directly to one > > of BIND ip addresses the QPS goes up to 50-60Qps. > > Those are very low numbers, for dnsdist but also for Bind (assuming you > mean 50-60k qps), on what hardware are you testing this?
