DNS performance...

Hi,

There are a large number of DNS servers available. See for example
http://en.wikipedia.org/wiki/Comparison_of_DNS_server_software

Does anyone know of good performance comparisons, especially for high
end applications with lots of data/zones and/or high query/update
rates?

Thanks,
Donald

OARC did a performance study of a few name servers in the context of
root zone scaling, but it should be generalizable:

Not sure of any comparison but I know BIND is widely used in the ISP
space and they tend to have lots of zones as expected.

Recursive or authoritative?

For recursive, there are pretty good graphs here:

Recursive or authoritative?

I'm actually interested in both. Thanks for the pointer!

One of the links below should have information about this:
- http://tin2.nixcartel.org/~devdas/presentation/dns-scalability.pdf

Please note this reports are not created by me.

Note this study compares BIND and NSD only, and under a very specific set
of conditions only, namely, serving a single large zone.

Thanks for these pointers.

For others who may be interested, the dns-scalability.pdf presentation
appears to be a superset of the dnsdb.pdf presentation.
