Could you tell us a bit more details? How exactly long did it take to
load the new configuration? Does that depend on specific add/remove
actions? e.g., does that change if you only add a single zone without
any deletion, or does that happen even for such a simple, small
change? Also, does that happen first time you reconfig the server, or
after several times of reconfig operation?
It would also be very helpful if you can file a bug report with the
set of your configuration so that we can reproduce it locally.
