Just to give you an idea, the total size of the zone files is around 250MB 
and as we do a full transfer every day these take about 2 hours per 
secondary.  This will change soon as we move to incremental updates, at 
which point we may well use NOTIFY.  From looking at our logs the largest 
number of zone files changes on one day is generally about 250,000 DNs 
being added or removed.
