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
resperf can be used with test files that include IPv6
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.
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.

resperf(1) man pages.

General support and discussion:
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
