UltraJSON is a fast and extendable JSON encoder and decoder written in pure C
Python bindings are available as the module ujson which currently supports the encode method.
Encoder benchmarks:
Preliminary benchmarks indicate this performance:
ujson encode : 58061.68741 calls/sec
simplejson encode : 19025.95344 calls/sec
cjson encode : 15308.70966 calls/sec
json encode : 2407.92068 calls/sec
See (python/benchmark.py) for further information.
NOTE: These benchmarks are preliminary!
