pandas-doctor
pandas-doctor finds the slow pandas lines in your code, rewrites them, and checks on your own data that the result is exactly the same. Then it tells you how much faster the rewrite was, measured, not guessed.
That's a real run on real data: examples/taxi/features.py on January 2024 of the NYC TLC yellow taxi trips (2.96 million rows), with the kind of loops a lot of notebooks have. The script took 96.6 s (M4 Pro, pandas 3.1.0 with pyarrow). pandas-doctor checked 5 rewrites on the script's own data, all identical and faster. After --fix the whole script runs in 1.64 s and prints exactly the same output. Full report in docs/taxi-run-full.txt.
