Serhiy might be right, it looks significantly worse with benchmarking:

lisroach$ python3 -m timeit "import json; json.dumps(['test'])"
100000 loops, best of 3: 2.73 usec per loop

lisroach$ ./python.exe -m timeit "import json; json.dumps(['test'])"
10000 loops, best of 5: 21.2 usec per loop

lisroach$ python3 -m timeit "import json; json.dumps(10000)"
100000 loops, best of 3: 2.49 usec per loop

lisroach$ ./python.exe -m timeit "import json; json.dumps(10000)"
20000 loops, best of 5: 16.3 usec per loop
