I have seen some benchmarking stat's on Bind [1] and NSD that compare FreeBSD 6.1 to 4.11, and 4.11 kick 6.1's ass and then wipes up the floor with it.
I'm going to be putting a DNS server in production soon and was planning to use FreeBSD, but now I'm wondering if OpenBSD would be a better choice from purely a performance perspective. I understand performance is secondary to security for this project, but I am curious what the numbers are in this specific case. Does anyone have stats on Bind performance on OpenBSD? (I saw the fefe page--looks old.) And when does performance really start to matter for a DNS server? Say I host 500 web sites and 500 email domains with "average" traffic, for some value of average. Is a limit of 15,000 DNS queries/second ever going to be a problem? If not, when could it become a problem? It will be my first DNS server, so I don't have a gut feel for this stuff yet.
