Hello, First, congratulation to all pypyers for the great work! As I've some spare time at work this week, I just tried to profile pypy running pystone interactively. The interactive session I used is below and the pickled result can be found bzip2ed at http://codespeak.net/~odie/profile-results-2005-10-20.pickle.bz2 Any suggestion for improving it is welcome :-) and actually any idea how to uses these information in any usefull way would be nice too :-) [pypy/pypy]$ python Python 2.4.1 (#2, Oct 8 2005, 00:22:59) [GCC 4.0.1 (4.0.1-5mdk for Mandriva Linux release 2006.0)] on linux2 Type "help", "copyright", "credits" or "license" for more information.
