[pypy-issue] [issue1091] list(xrange) is slower in PyPy 1.8 than in CPython 2.6.5

[Richard Barrell]

New submission from Richard Barrell <rchrd at brrll.co.uk>:

I'm using the Linux 64-bit binary PyPy 1.8 from here: https://bitbucket.org/pypy/pypy/downloads/pypy-
1.8-linux64.tar.bz2
and Python 2.6.5 from the repositories on Ubuntu 10.04. The machine that I'm running on is a Core 2 Duo 
laptop with 4GB of RAM, running at 2.10GHz.

>>> import time; t1 = time.time(); _ = list(xrange(10000000)); print time.time() - t1

And now for something completely different: ``PyPy is Shirt Origami research''
