dnsperf and resperf are free tools developed by Nominum/Akamai (2006-2018)
and DNS-OARC (since 2019) that make it simple to gather accurate latency and
throughput metrics for Domain Name Service (DNS). These tools are easy-to-use
and simulate typical Internet, so network operators can benchmark their naming
and addressing infrastructure and plan for upgrades. The latest version of
the dnsperf and resperf can be used with test files that include IPv6
queries.
dnsperf "self-paces" the DNS query load to simulate network conditions.
New features in dnsperf improve the precision of latency measurements and
allow for per packet per-query latency reporting is possible. dnsperf is
now multithreaded, multiple dnsperf clients can be supported in multicore
systems (each client requires two cores). The output of dnsperf has also
been improved so it is more concise and useful. Latency data can be used to
make detailed graphs, so it is simple for network operators to take advantage
of the data.
resperf systematically increases the query rate and monitors the response
rate to simulate caching DNS services.
See also the dnsperf(1) and resperf(1) man pages.

General support and discussion:
dnsperf and resperf read input files describing DNS queries, and send
those queries to DNS servers to measure performance.
dnsperf requires a couple of libraries beside a normal C compiling
environment with autoconf, automake, libtool and pkgconfig.
- OpenSSL - for TSIG support
- Concurrency Kit - for atomic operations
- LDNS - optional for dynamic update support
- nghttp2 - for DNS-over-HTTPS support using HTTP/2

The source tarball from DNS-OARC
comes prepared with configure:
tar zxvf dnsperf-version.tar.gz
cd dnsperf-version
./configure [options]
make
make install
git clone https://github.com/DNS-OARC/dnsperf.git
cd dnsperf
./autogen.sh
./configure [options]
make
make install
