Hi,
If you are going the IaaS route, definitely checkout KnotDNS project. According to their benchmarks [1], it does much better than other DNS servers in about every workload.
The problem with KnotDNS/Yadifa/NSD is that they are too optimized for servers with a small number of zones containing large numbers of records, usually delegation-only. That is the use of TLD registries, but not the use case of registrars... ... all those 3 are getting better in supporting large number of zones with small number of records, but the canonical solution in that space is Power DNS. Things that TLDs usually don't like, SQL-backend for instance, makes perfect sense for this use case. Note that the only workload they tested is serving the root zone, not multiple number of zones with variable number of RR-sets... so aligning the testing with the actual use case is crucial to make good decisions. What I strongly support, though, is getting out of the BIND comfort zone. Rubens
