simplejson is not the only JSON library out there. For example, there's
python-cjson, which is written entirely in C:

<http://pypi.python.org/pypi/python-cjson>

There's also an enhanced version of it:

<http://python.cx.hu/python-cjson/>

I think simplejson has some small, optional C bits that will improve
performance if you compile them.

Also, be aware that I think simplejson is being integrated into the
stdlib in Python 2.6.

Also, simplejson and python-cjson might not be entirely compatible:
there's one character that one escapes and the other doesn't, or something.
