Hi Bert!, I've run again 1000 domain test with logging disabled (just in case). The results look pretty much the same: http://pastebin.com/Nsjhjnx3 Tried a cold cache with 80k domains, it was a disaster, I couldn't let it finish. The configuration: ---- local-address=<ip1>,<ip2>,<ip3> allow-from=<test1>,<test2>,<test3> threads=10 --- I'll double check with the networking guys, This server will use a secondary public IP, but I see that the queries get out with the base private IP, so it's possible that the edge NAT is causing this. I'll keep you updated.
