External bottlenecks - poliastro/poliastro GitHub Wiki

Recollection of bottlenecks coming from external libraries and dependencies:

• Quantities from astropy.units are too slow
  • Possible replacement: https://github.com/astrojuanlu/fastunits/
• Coordinate frames astropy.coordinates try to do too many things at once: they contain both the coordinates (hence having to implement lots of numpy.ndarray methods) and the transformations.
  • Possible replacement: https://github.com/astrojuanlu/astropy/commit/f7873c5af6290bcdf280ed4e641776864f5ae481
    • In summary: coordinate transformations should be decoupled from coordinates themselves
• Integration methods from SciPy are too slow
  • Possible replacement: https://github.com/hgrecco/numbakit-ode/, https://github.com/poliastro/poliastro/issues/1042
• Plotly on JupyterLab keeps breaking from time to time
• Sphinx and its extension ecosystem are very difficult to understand
