django-picklefield slow compared to a naive solution using jsonpickle

[araichev]

Hi, i use django-picklefield in a project of mine and noticed that it's quite slow compared to pickling an object using jsonpickle (https://github.com/jsonpickle/jsonpickle), storing the result in a TextField, and unpickling the TextField back into a Python object. Do you know what's up with that?

I don't have any benchmarks to show for at present, but i'll make some when i get a chance. Thought i'd raise the issue now, though.

Benchmark would be greatly appreciated since we use the C bindings when available while from I could see jsonpickle is entirely written in Python.

Did you try using the protocol kwarg of PickledObjectField to use the latest version?

It also helps to set the protocol to highest. It's not the most compatible mode, but the fastest

PickledObjectField(null=True, protocol=-1)

Closing due to the lack of benchmarks.
