[pypy-issue] [issue1102] This program takes longer to run under pypy-1.8 than under 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.

The program (workhorse.py) is attached. 

With CPython 2.6.5:

richyb at figgy:~$ time python workhorse.py 
start
end
5.36431598663

real    0m5.386s
user    0m5.350s
sys     0m0.020s

with PyPy 1.8:


richyb at figgy:~$ time pypy workhorse.py 
start
end
9.53850102425

real    0m9.597s
user    0m9.480s
sys     0m0.080s
