python - Should I use Pickle or cPickle? -

-

python has both pickle , cpickle modules serialization.

cpickle has obvious advantage on pickle: speed. what, if any, advantage pickle have on cpickle?

the pickle module implements algorithm turning arbitrary python object series of bytes. process called serializing” object. byte stream representing object can transmitted or stored, , later reconstructed create new object same characteristics.

the cpickle module implements same algorithm, in c instead of python. many times faster python implementation, not allow user subclass pickle. if subclassing not important use, want use cpickle.

source of above information.
