    # Extract tidal constants: amplitude (m), phase (deg), and constituent names
    amp, phase,  = pyTMD.io.FES.extract_constants(lon, lat,model_files=model_files,version='FES2022')

    print(amp,phase)

I'm interpolating the amplitude and phase of 5 points, but the speed is a bit slow. Is there any way to increase the interpolation speed?

Try including the crop option. Also the default interpolator is a bivariate spline. Setting method=linear can be faster in some instances.

I am also working on the data access patterns (as noted in #452 and #478), but most of my thoughts are long-term goals
