Benchmarks — Python by release

Y Line chart of Time (ms), grouped by version, split by benchmark, filtered to outlier == false, sorted by version_idx, with 1 computed expression column.

Mean time of each Python benchmark case across every published Perspective release.

Benchmarks — Python by release: Y Line chart of Time (ms), grouped by version, split by benchmark, filtered to outlier == false, sorted by version_idx, with 1 computed expression column.

Data

Perspective's own benchmark results for perspective-python — the native engine, driven from a Node.js client over WebSocket — as published with each GitHub release: every timed iteration of table construction, streaming updates, pivots, expressions, joins and serialization over the Superstore dataset, for the current and prior releases, measured by CI on a GitHub Actions ubuntu-22.04 runner.

Loaded from /data/benchmark-python.arrow as arrow into the perspective-server engine.
