Faster copying of composite new-class objects

[Alex]

Hi,

My program requires copying thousands of composite new-class objects. I
found that the following: objCopy=cPickle .loads(cPickle. dumps(obj,
protocol=2)) works about 4 times faster than
copyObj=copy.de epcopy(obj). Is there any way to do it even faster?

All objects have slots, __getstate__ and __setstate__.

TIA,

Alex

At a wild guess: writing custom serialisation functions using module
marshal?
