Python’s Weak Performance Matters
Except Pandas and SciPy use libraries written in CXX or Fortran and not pure python so speed is not really an issue with them usually

pandas.read_csv is kind of abysmally slow, unfortunately. There are a couple of alternatives, but nothing has really taken hold.
Dask exists, but not everyone can run a distributed system to read a multi-gigabyte csv.

Have you tried paratext from wiseio? I have had good experiences with it.
