Re: [knot-dns-users] signing parameters for number of cores

Hi Daniel, thanks a lot for the answer.. In my eyes it would be helpful if it could be possible to speed up the signer with more cores.. But .. in my eyes it is not a showstopper. But a good information for buying the right processor in a server if we decide to use knot for signing.. If I have a look to your issue I fear that there wouldn't be any modification in this direction.. best regards -- Christian Petrasch Senior System Engineer DNS/Infrastructure IT-Services DENIC eG Kaiserstraße 75-77 60329 Frankfurt am Main GERMANY E-Mail: petrasch(a)denic.de http://www.denic.de <http://www.denic.de/> PGP-KeyID: 549BE0AE, Fingerprint: 0E0B 6CBE 5D8C B82B 0B49  DE61 870E 8841 549B E0AE     Angaben nach § 25a Absatz 1 GenG: DENIC  eG (Sitz: Frankfurt am Main) Vorstand: Helga Krüger, Martin Küchenthal, Andreas Musielak, Dr. Jörg Schweiger Vorsitzender des Aufsichtsrats: Thomas Keller Eingetragen unter Nr. 770 im Genossenschaftsregister, Amtsgericht Frankfurt am Main Von:        daniel.salzman(a)nic.cz An:        "Christian Petrasch" &lt;petrasch(a)denic.de&gt; Kopie:        knot-dns-users(a)lists.nic.cz Datum:        11.09.2018 20:36 Betreff:        Re: [knot-dns-users] signing parameters for number of cores ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Hi Christian, Unfortunately, the present implementation of zone signing cannot utilize more CPU cores per one zone. The "background-workers" option is useful just for setting the number of different-zone events which are executed concurrently. We even have a very old issue on this https://gitlab.labs.nic.cz/knot/knot-dns/issues/186 Is it a serious limitation for you deployment? Regards, Daniel On 2018-09-11 11:52, Christian Petrasch wrote:
