[pypy-issue] [issue1630] Matrix dot product ~5x slower in PyPy

[Tibor Kiss]

Tibor Kiss <tibor.kiss at gmail.com> added the comment:

I measure even bigger difference on OS X 10.8.5. 
Numpypy&Pypy is roughly 2 orders of magnitude slower than Numpy&cPython.

See the testcase attached.

% python2.7 matrix_dotprod_test.py
0.414262056351
% /opt/pypy-2.2-osx64/bin/pypy matrix_dotprod_test.py
58.8765079975
