I have a Centos 4.0, bind-9.2.4-2 as a master and and FC2 bind-9.2.3-13 slave setup. Their seem to be a delay on the Centos 4 when asking for anything that is not in its cache. Doing some tcpdumps I see the AUTH response came back, but like a 3 second delay after that before server sends response to client. Both server have the same config other than one being a master and the other a slave. Their are no delays on the FC2.
Googled on this with no joy.
Any ideas?

I rebuilt the FC2 src rpm and replace the stock Centos 4 rpms with it, performance is fine now.

Just a gut guess here Ted, but try disabling IPv6 support in your kernel on the CentOS4 box by putting:
alias net-pf-10 off
in your /etc/modprobe.conf and then rebooting. That pause smells suspiciously like the same pause you used to get from Mozilla when IPv6 was first introduced in...FC2? or whenever. Give the official CentOS4 bind package a shot then, see what happens.
