The following not significant results are hidden, use -v to show them:
call_method, call_method_slots, call_method_unknown, fastunpickle, iterative_count, json_dump, json_load, nbody, pidigits, regex_effbot, regex_v8, richards, simple_logging, startup_nosite, threaded_count.


In short, any difference is in the noise.
