[Django]-Django caching – Pickle is slow

If you are currently just using pickle, might I recommend cPickle which is purported to be up to 1000 times faster.

ultrajson to the rescue!

In [1]: from string import letters

In [3]: import ujson

In [5]: import cPickle as pickle

In [7]: import random

In [8]: def random_string(n=10): return ''.join([random.choice(letters) for _ in xrange(n)])

In [9]: DATA = {random_string(): list(range(1000)) for _ in xrange(1000)}

In [12]: %timeit -r 3 -n 100 ujson.dumps(DATA)
100 loops, best of 3: 89.2

In [13]: %timeit -r 3 -n 100 pickle.dumps(DATA)
100 loops, best of 3: 285 ms per loop
