Performance penalty for uncompiled code

$ pip3 install nuitka
$ python -m nuitka --version
0.6.0.3 
Python: 3.6.6 (default, Sep 12 2018, 18:26:19) 
Executable: /usr/bin/python
OS: Linux
Arch: x86_64

(same behavior with 0.6.1rc6)

# test.py
import time
import re

start = time.time()
for i in range(2000000):
    re.match('xyz', 'asdf')    
print(time.time() - start)

$ python test.py
4.666041374206543

$ python -m nuitka --run  test.py
8.2843918800354

Similar performance penalty also with os.fspath for example.

Well. The fact that compiling as extension module solves the problem is actually good news for me. Just have tested that and it really works without a slowdown. Thank you very much!
