I wonder if something like https://paulbradley.org/sqlite-test-data/ https://paulbradley.org/sqlite-test-data/ could be used to generate the test data in sqlite3 directly, and if it would be any faster. (It would likely be faster for other DB engines, because there is network overhead in the communication between the program and the DB; no such things for sqlite).
