[pypy-dev] PyPy 2x slower using cpickle

3 Jul 2013

      Hello,

We also found a case where PyPy is 2x slower than CPython. The following 
code:

<<<<

import cPickle

fileIter=open("pypytesting", "w+b")
mylist = ["qwerty"] * 100

for i in xrange(1000000):
         cPickle.dump(mylist, fileIter,1)
...
...
...
...
Runs at:
	CPython 2.7.3:  13.114 sec
	PyPy nightly:    29.239 sec

[Warning: it'll produce a file (pypytesting) that is 205 MB in size]

Kind regards,

lefteris.
