I have not the slightest clue why, I had suspected that rndc reconfig would be much faster, especially is there is no altering in the config at all. How are you testing this? 'time rndc reconfing'? Yes. Or do you stop answering queries and time that? No. How long do

Why not try the latest version, really? Pick a test host. Install 9.8.1+. Time it again. Then let's talk. Such things take time. Did it now, but it didn't changed anything. It seemes that the performance optimization (which is mentioned in the releasenotes for startup) doesn't affect

I just updated a couple of my DNS-servers from the rather old version 9.4.1 to a newer version 9.8.0-P4. After this I have problem with outages. Looking into it, I found that the time for a rndc reload has nearly doubled! This has been pointed out to me before; do you really need

It is not clear in your question, are you use rndc reload or rndc reload zone.name? Latter will be faster in case if you change one or few zones in one pass of your updating-script. I generate from my database the complete named.conf, especially including new zones and then trigger a rndc

In this case rndc reconfig should be sufficient. This command tells BIND to re-read config file and load all new zones without touching any previously loaded zones. This was my understanding (after reading the text from rndc) as well. But to my surprise: I tested rndc reload against rndc
