How can I reduce the execution time of numpy.linalg.norm()?

[12345data]

While executing the script found that the numpy.linalg.norm() process is taking much time for execution. I have tried by reducing the number of points passed to the function and got better throughput but not such satisfiable for me. In the current situation, it is taking about 3-4 seconds for one comparison. How can I reduce it to below 1 second without much compromising the accuracy.

Does your experiment have good performance? about multi-sensor images?

Can you try with this function https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.distance.cdist.html ?
