When all the Windows PC's are switched to our resolver, bind stops responding. rndc querylog shows queries coming thru, I changed tcp-clients from 1000 to 10000 but DNS seems lagging, so we switched back to the original Windows Domain resolver. Besides increasing open files tuning, what TCP / sysctl or named.conf settings can be set to optimize / speed up DNS queries? Because it seems that Windows clients use TCP instead of UDP when looking at netstat on the server.
