On pure integers like this:: divisors(10000000) times on my test machine are 1.12s for cpython, 0.091 for pypy (that's 12x speedup). on divisors(Integer(10000000)) speedups are less impressive (5s for CPython, 3s for PyPy). Which one did you try on Cython? Cheers, fijal -- You received this message because you are subscribed to the Google Groups "sympy" group. To post to this group, send email to sy...@googlegroups.com.
