Thanks for valuable feedback. That's exactly what we were looking for. We will be
fixing those issue before final release and adding regression test for those as well. I am
quite sure we already did successful work on speeding the loading of hundred of thousands
of zones and not just tens of thousands.

Hello Knot developers,
I configured an instance of Knot 1.2.0rc3 with 5174 slave zones, and
started it. I wanted to see how long it would take to transfer all the
zones in. It has been running for about an hour, and it still hasn't
managed to load all the zones from its master. I'll pick just one zone
as an example to show how long it took:
# grep apnic.net /var/log/knot/knot.log

From the time Knot decided it needed to bootstrap apnic.net, to the time
it actually transferred the zone in, it took 67 minutes! All that while,
it was responsing with SERVFAIL for the zone.
While the zone "apnic.net" has now been loaded, Knot is still busy
loading many of the other zones. I can't tell how far it is. Perhaps
there could be a command for knotc, called "zonestatus" which would
print out a list of all configured zone, and their statuses.
I understand that transferring in lots of zones takes time. However, if
I start an instance of BIND with the same slave zones, it can transfer
them all in within about 15-20 minutes. Knot appears to be much slower
in comparison.
Do you have any suggestions for speeding things up?
Regards,
Anand
