I notice the release of Knot DNS version 1.0.0 by the CZ Internet community. This is a high performance authoritative name server software supporting DNSSEC and NSEC3. When tested on a 4-core Intel Xeon X3430, 2.40 GHz, 2 GB RAM, running Linux 2.6.38-11, x86_64, Knot DNS can handle 200k queries per second while BIND 9.8 can handle slighty half of Knot DNS. Knot DNS is a perfect choice of secondary level domains (STD) or even TLDs. However, there is still a long way to go compared with Nominum Authoritative Name Server (ANS). This software has a stunng peformance of processing 1 million queries per second if running on same hardware config. Nominum ANS is the king of name server software !!
