Python performance profiling using cProfile

Generate the profile:
$ python -m cProfile -o phoney.cprof phoney.py

Then, transform it into something readable by Kcachegrind:
$ python pyprof2calltree.py -k -i /home/para/dev/metis_unicorn/script/phoney.cprof

Or read it directly using RunSnakeRun

Bear in mind that cProfile does very badly with multi-process.
