we made a recurive resolver (Cent OS 7, 8GB RAM ,250 GB Hard disk and network speed is also good ) . It reply in 1200 msec and 1800 msec (which is very slow). if it gave Reply by Cache (80 msec or 76 msec). so i want to know about, How can i improve my recursive resolver speed. and If we apply syslog (it is a centralised logging of bind) . then any profit for recursive resolver.
If you have anything like DNS fixups set on your routers, turn it off now. Those don't offer any real fixups, but they do mess up DNS service instead.
In order for us to help you better, you need to provide more information. What makes you think The recursive resolver is slow? Do you have syslog? Is the BIND instance slow, or is it the operating system (low RAM? Slow disk?) or is this a network-related issue?
