The performance penalty is the largest bottleneck of Python code. It
can be seen from the following minimal example:

werner@X10DAi:~$ time python3 --version >/dev/null

real    0m0.086s
user    0m0.065s
sys    0m0.027s
werner@X10DAi:~$ time perl --version >/dev/null

real    0m0.003s
user    0m0.003s
sys    0m0.000s
