Hum, so for an usability point of view, I think that the best to do is to ignore the option if Python has a JIT.
On CPython, --duplicate makes sense (no?). So for example, the following command should use duplicate on CPython but not on PyPy: python2 -m perf timeit '[1,2]*1000' --duplicate=1000 --compare-to=pypy Victor _______________________________________________ Speed mailing list Speed@python.org https://mail.python.org/mailman/listinfo/speed
