Summary: Hint for speeding up cPickle

Initial Comment:
There is a strange behaviour in cPickle (in Python 2.2.1).
For big serialized file, the following:

        cPickle.loads(open("my_file").read())

can be much (e.g. 7 times) faster than:

        cPickle.load(open("my_file"))

It seems that cPickle use unbuffered reading or what ?
The pickle implementation doesn't have this behaviour,
and can even be
faster than the C one!
