This is simply wrong. You should be using cjson.decode(), not
cjson.encode().
If you do so, you will see that cjson tajes as much as memory as
simplejson and is actually a bit slower.
Looking at your json file, I would have a couple of suggestions:
- don't quote integers and floats, so that they are decoded as Python
ints and floats rather than strings
- if the same structure is used a large number of times, don't use
objects, use lists instead
