Assuming that the zones were mostly up to date, it was serial-query-rate.
Also, FYI, you're getting pretty close to the point where the
master/slave configuration is going to become a bottleneck. If you plan
to grow much beyond this point you should start looking at making all of
your systems masters and using an out of band method to update the zones.
Nothin' ever doesn't change, but nothin' changes much.
