I'm wondering if > the C extension didn't build for some reason. I've tested json vs. cjson and ujson on Python 2.7.6 on OS X 10.10.2 and Python 2.7.3 on Debian Jessie. In both cases, the standard json module was noticeably slower (and "import _json" does work). On my Debian box I also tried using simplejson directly, and it was also faster than json.
