New issue 2517: Example scientific numpy code 6x slower in pypy https://bitbucket.org/pypy/pypy/issues/2517/example-scientific-numpy-code-6x-slower-in
lesshaste: The attached numpy code computes the permanent of a matrix and is about 6 times slower in pypy 5.7 than cpython. This is a problem in real scientific code so we have resorted to using cython currently. time python test.py -3.11279519223e-07 real 0m5.085s user 0m5.180s sys 0m0.304s time bin/pypy test.py -3.11279519223e-07 real 0m33.465s user 0m33.412s sys 0m0.036s _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
