I'm stuck on a problem where I want to use marshal for serialization (yes, yes, I know (c)Pickle is normally recommended here). I favor marshal for speed for the types of data I use.
However it seems that marshal.dumps() for large objects has a quadratic performance issue which I'm assuming is that it grows its memory buffer in constant increments. This causes a nasty slowdown for marshaling large objects. I thought I would get around this by passing a cStringIO.StringIO object to marshal.dump() instead but I quickly learned this is not supported (only true file objects are supported). Any ideas about how to get around the marshal quadratic issue? Any hope for a fix for that on the horizon? Thanks for any information. -- http://mail.python.org/mailman/listinfo/python-list
