@gwin-zegal , thank you for using our new feature and reporting the issue. I confirmed the poor performance of interp.

I will look inside later, whether problem is on our code or upstream (scipy.interpolate).

A possible workaround for your code is to change python arr.interp({'tension': new_tension, 'resistance': new_resistance}) to python arr.interp({tension': new_tension}).interp('resistance': new_resistance}) but it does not solve all the problems.
