If your Python programs heavily use Pandas and Numpy, could there still be speed benefits to translating them to Nim?

Generally, projects created by Mamy Ratsimbazafy (mratsim) are a good start since he's very adept at optimisating data science-related libraries.
You might want to ask in the #science channel of the Nim Discord server since although it's often quiet, that's where people working on these repositories hang out.

The big issue Nim faces isn't performance but rather the relative community sizes, and thus how many libraries are available (and also how much help you might find when you run into problems).
