Probably. I'd like to get Michael's feedback... I have not heard of
this from anyone else.... have either of you?

I've been experimenting with loading a large number of master zones

noticed that 'rndc reconfig' with this many zones loaded can take a
very long time to determine that it has little or nothing to do.
Worse, the server stops answering other requests for the duration,
in both threaded and non-threaded builds -- I'm testing with 64 bit
builds of both 9.7.0-P1 and 9.7.1-P2.
In the best case, a reconfig will take about 40 seconds to complete,
and stalls the server for most of that time. Loading zones in bulk
is substantially slower, but is less of an issue for the intended
use, and is more or less limited by the speed of the storage.
My next step is going to be to experiment with the rndc addzone/
delzone feature in the 9.7.2 betas, which hopefully should avoid any
need to attempt a reconfig during normal use. That aside, is there
anything else I could be doing to speed things up?
