Perl version:v5.32.0
Python version:3.8.5
I have a little disappoint about the result:
Perl slower a lot than python.

Perl Code(

Python Code(
#!/home/weizhong/tools/Python-3.8.5/python import numpy as np X = np.zeros((1000,500,500)) Y = np.ones((1000,500,500)) Z1 = X+Y Z2 = X/Y

#!/bin/csh -f echo "Python"; time ./ echo "Perl"; time ./ echo "Python"; time ./ echo "Perl"; time ./
