Re: [knot-dns-users] Parallel dynamic DNS updates

Hi Ondřej, We have a master server which receives only updates and a farm of slave servers (ifxr), which handle reads. The issue is scaling master server, 1 zone, which is 80M (text), currently we cannot get more than 200 QPS updates from BIND on 4-way SMP Linux machine. Each update request is usually 1-2 records. And usually we don't have parallel updates which are working on the same record. Our target is 10x from current - i.e. ~1G single zone, which does ~2-4k QPS of updates. Actually as much as possible in terms of QPS, CPUs & memory is not an issue - we can get stronger machine. Thanks, Alex. -----Original Message----- From: Ondřej Surý [mailto:ondrej.sury@nic.cz] Sent: 28 May 2014 11:23 To: Alex Massover Cc: knot-dns-users(a)lists.nic.cz Subject: Re: [knot-dns-users] Parallel dynamic DNS updates Hi Alex, could you describe your scenario in more detail? How many zones are we talking about? How big the zones are? How many updates per second per zone?
