What do people use/recommend for high performance name serving?
I currently have a few servers running bind9 (9.2.4-1sarge2) serving
an average 750 requests per second running on Debian/sarge.
kernel-2.4.32 (the stats say: low: 0.00, peak: 2500, avg: 750)
We're either going to replace these, or if there is something we can do
to poke it and make them happier, we'll do that.
take a look at dnscache:
It's a caching-only server, so you don't get the overhead of using a
full-featured bind. I have a couple of them running for years without any
I can't really recommend dnscache because it breaks the DNS protocol in
various ways, but the *real* problem is it doesn't do round robin, so your
dns server always returns the same answer instead of round robin-ing
through A records and such that are identical except for the content.
