I suggest `--duplicate 10` option.

While it is good for start point, please don't forget we need "application"

Even if some function call overhead can be 3x faster, if it takes only 3%
of application execution time, total execution time only 1% faster.
It's too small to accept PEP 580 complexity.

Realistic application benchmark demonstrates not only "how much faster",
but also "how important it is".
