I'm using python -m cProfile -s calls myscript.py

python -m cProfile -s percall myscript.py does not work.

The Python documentation says "Look in the Stats documentation for valid sort values.": http://docs.python.org/library/profile.html#module-cProfile, which I cannot find.

-s only uses the keys found under sort_stats.

calls (call count)
cumulative (cumulative time)
cumtime (cumulative time)
file (file name)
filename (file name)
module (file name)
ncalls (call count)
pcalls (primitive call count)
line (line number)
name (function name)
nfl (name/file/line)
stdname (standard name)
time (internal time)
tottime (internal time)

Here's an example

python -m cProfile -s tottime myscript.py
