Benchmarks
qsv's benchmark suite runs 259 benchmarks on a 1,000,000-row × 41-column, 520 MB
sample of NYC's 311 data, timed with hyperfine
(2 warmups + 3 timed runs each). See
scripts/results/README.md
for the methodology and the raw CSVs.
➡️ Open the interactive benchmark dashboard
The dashboard is rendered by qsv's own viz command and is fully interactive (hover for
values, zoom, download PNGs). It covers the with/without-index advantage, the sqlp
schema-cache knob, throughput across every release, deep-dives into the two flagship
commands (stats and frequency) showing they grew features without losing speed, and
this release's biggest speedups.
Note: cross-version numbers are not strictly apples-to-apples — commands gain features over time. Treat the historical trend as a broad trajectory, not an exact speedup.
Last generated for qsv 21.1.0 (aarch64-apple-darwin). Regenerate with
python3 scripts/gen_benchmark_viz.py and copy this page's link — the dashboard itself
redeploys to GitHub Pages automatically on push to master.
