Bug description:
  Python 2.6 ships 'json' module that is very slow because it's written
  in pure Python. Python 2.7 updated [1] its 'json' module from
  simplejson PyPI repo with a version that is based on C extension (and
  quick). Quoting: "Updated module: The json module was upgraded to
  version 2.0.9 of the simplejson package, which includes a C extension
  that makes encoding and decoding faster. (Contributed by Bob Ippolito;
  issue 4136.)"

  We should strive to use simplejson library when running on Python 2.6.
