Hello Ciro, Your server has 8 cores. I don't know if the Recursor benefits from hyperthreading (would be good to know). If you run the Recursor with threads=4 you have only 4 cores left for the clients. I got the best result with 4 Recursor threads and two clients. But I think you can improv

[Pdns-users] Recursor QPS ceiling

2014-12-17 Thread Ciro Iriarte
Hi!, could anybody achieve more than 100k QPS on a recursor while hitting cache?. I only run two tests so far and in both cases the ceiling was around 100k QPS. The machine seems to be able to take more beating, maybe I just need more clients or there's some kind of logic limit. Any comments?.
