Why it is much slower when using python -m scoop deap_ga_onemax.py

[sc1101]

Hello!
When I used "python -m scoop deap_ga_onemax.py" to run the example file "deap_ga_onemax.py", I found that is much slower than just used "python deap_ga_onemax.py" to run it.
Why is that happened? What should I do to use scoop to speed up the code of "deap_ga_onemax.py"?
