A profiler is designed to show where execution time is spent within one run.
And with PyPy, the line-by-line tracing is likely to kill any optimization made by the JIT
To compare execution of different systems, don't use cProfile,
just measure the time it takes to execute your function (in a loop, probably).
For my part, I use the Python timeit module, or just the unix "time" command.
