Are the response times the same in the local network, and in the server console itself?  Just to isolate if the problem is in the server side, or on the network side which many has already suggested.

Aihe: Fwd: Re: recursive resolver

Thank you  very much sir for replying

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.



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?
