Speaker: Stefan Wunsch (KIT - Karlsruhe Institute of Technology (DE))

Benchmark of the ROOT.Numba.Declare feature.pdf

Action items:

- Remove nullptr checks

- Check that we actually optimize the code, .e.g., with an empty but large loop

- If none of this brings the ratio much closer to 1, Axel will go into debug mode :)
