I'm porting a python NLP module to nim,it results 4 times slower than python version.
It's for Chinese word segment task. you can see the main test file(takes about 5 second): [https://github.com/bung87/finalseg/blob/master/tests/test2.nim](https://github.com/bung87/finalseg/blob/master/tests/test2.nim) and python version test(takes about 1 second): [https://github.com/bung87/finalseg/blob/master/tests/speed.py](https://github.com/bung87/finalseg/blob/master/tests/speed.py) the original python module file: [https://github.com/fxsjy/jieba/blob/master/jieba/finalseg/__init__.py](https://github.com/fxsjy/jieba/blob/master/jieba/finalseg/__init__.py) nim :Nim Compiler Version 0.18.0 [MacOSX: amd64] python:Python 3.6.5 (default, Jun 17 2018, 12:13:06) cup:2.7 GHz Intel Core i5 ram:8 GB 1867 MHz DDR3
