net-benchmark
fast, extensible network benchmarking — dns, http, ssl, and distributed load testing from a single cli.
pip install net-benchmark
pip install net-benchmark[pdf] # with pdf export
successor to dns-benchmark-tool — fully backward compatible.
dns-benchmarkcommand still works as an alias.

since 0.5.2, load can be generated from several parallel workers — separate processes
on one machine, or separate machines entirely — with a synchronised start and a
statistically correct merge. merge-load-test recomputes p95_latency and p99_latency
from the merged latency histogram rather than averaging per-worker percentiles;
std_latency, jitter, consistency_score and the phase p95s do not survive a merge and
are rejected as unknown metrics, so evaluate those per worker.
