New issue 1782: Test case where pypy is more than 4x slower than CPython
https://bitbucket.org/pypy/pypy/issue/1782/test-case-where-pypy-is-more-than-4x
estama:
I've found a small example where PyPy is slower (more than 4x) than CPython. The example calculates all the possible groupings of a list of values. I've attached the example's code.
Timings:
time python allgroups.py
20.75s user 0.04s system 99% cpu 20.820 total
time pypy allgroups.py
97.31s user 1.07s system 99% cpu 1:38.55 total
