Those are very low numbers, for dnsdist but also for Bind (assuming you mean 50-60k qps), on what hardware are you testing this? Is this a VM? > we have tried both rpm install of dnsdist, compiling from source and > even comiling the concur version but all with similar results, ie when > resperf tests go through dnsdist the results are much lower in terms of qps. Knowing the exact version of dnsdist would help a lot. Did you read the tuning guide ? At the very least you should set setMaxUDPOutstanding(65535). You are also using a single thread for receiving UDP queries which might not be what you want, although you should get much more than 15k qps even with a single thread. > OS is Centos7 in all servers, tweaked all settings for file limits, udp > connections etc. Did you disable any firewall? Remove any connection tracking modules? It would be very useful to know exactly what you tweaked. : https://dnsdist.org/advanced/tuning.html Best regards, -- Remi Gacogne PowerDNS.COM BV - https://www.powerdns.com/
