[pypy-dev] deepcopy slower in PyPY ?!

 Hi to all

I've benchmark/profile  some code (PyWPS API) and PyPy-c is 2/3x times
slower than CPython.  This was done in a virtual machine using x86_64

The code being benchmark spends most of the time making calls to
copy/deepcopy.  I've found that this was an issue in PyPy 1.6
(https://bugs.pypy.org/issue767), but the issue has been closed. So I've
downloaded the latest dev version but PyPy-c continues to be slow
compared to CPython.

Does anyone has extra information on this issue ?

Thank you
