> When pickle is used to pickle the data, there is a significant slowdown > Both pickle and cPickle show a slowdown when data pickled in python 2.6 is unpickled in python 2.7: This sounds rather weird. Presumably the structure of the pickle streams shouldn't have changed from 2.6 to 2.7. You can use the pickletools.dis() function to disassemble a pickle stream, and examine whether there are any differences between the various files.
