Pypy3 Vs Python 3
By IsaaMaster, history, 3 years ago, In English

Hello All,

Just out of curiosity what is the difference between Pypy3 and Python3 in terms of runtime? I know generally Pypy3 is faster but sometimes Python 3 is faster. Is there a way of knowing beforehand which will be faster?

PyPy3 is much faster than Python3 for just about everything. In my experience, the main time it's slower is just for I/O.

    pypy uses alot more memory tho. Also sometimes it does perform worse than cpython
