Jan Stránský proposed the following answer:
> when you say rewrite the code in C++, how would this work?

- write your function in both c++ and python (have a look how, e.g., utils.sumForces is implemented [1,2,3])
- you have to (re)compile yade from source [4]
- then you can call your faster c++ function from python
