Pickle uses python class-based implementation while cPickle is written as C functions. As a result, cPickle is many times faster than pickle. Pickle is available in both python 2.
What is cPickle used for?

How do I Unpickle a file?
You can use the loads() method to unpickle an object that is pickled in the form of a string using the dumps() method, instead of being stored on a disk via the the dump() method. In the following example the car_list object that was pickled to a car_list string is unpickled via the loads() method.
What kind of information is best stored using the cPickle module?
cPickle supports most elementary data types (e.g., dictionaries, lists, tuples, numbers, strings) and combinations thereof, as well as classes and instances. Pickling classes and instances saves only the data involved, not the code.

Serialization refers to the process of converting a data object (e.g., Python objects, Tensorflow models) into a format that allows us to store or transmit the data and then recreate the object when needed using the reverse process of deserialization.

Are pickles faster than JSON?
JSON is a lightweight format and is much faster than Pickling. There is always a security risk with Pickle. Unpickling data from unknown sources should be avoided as it may contain malicious or erroneous data. There are no loopholes in security using JSON, and it is free from security threats.

What is serialization used for?
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
What is pickle in machine learning?
The pickle module keeps track of the objects it has already serialized, so that later references to the same object won’t be serialized again, thus allowing for faster execution time. Allows saving model in very little time.
