The configuration and results of DoQ vs DoT DNS resolver benchmark

dns_server_configs

contains configuration of each DNS resolver measured in this benchmark.

systemd_configs

contains the systemd unit configuration of the DNS resolvers. Knot Resolver does not have a systemd unit configured because it didn't require one. running Knot Resolver with a manager process means that any worker failures that might occur will be resolved simply by the manager restarting said worker.

measurements

contain the complete benchmark results from a test which was run on the 16th of october 2025. The measurement directory contains many subdirectories which might seem to have a cryptic names. Here is the semantic meaning of the directory names

bench_<protocol>_<DNS server>_<number of clients>

where the DNS server is an integer number which corresponds to the last number of the IP address the DNS resolver listens on

bench_<protocol>_1_... is kresd (single worker)

bench_<protocol>_3_... is Unbound

bench_<protocol>_4_... is RouteDNS

bench_<protocol>_5_... is Knot Resolver run with manager

these IP addresses can be found in the dns_server_configs/*.conf

Each of these directories contains:

• 30 files storing the benchmark results.
• runs.json where these results are aggregated
• averages.json where these are averaged

run_bench.py

is the python script used to perform the tests the current configuration (seen at the top of the script) runs for approximately 10 hours.
