Better Profiling Support for PyPy
As PyPy is getting more and more usable, we need better tools to use to work on certain applications running on top of PyPy. Out of this interest, I spent some time implementing the _lsprof module, which is a part of the standard library since Python2.5. It is necessary for the cProfile module, which can profile Python programs with high accuracy and a lot less overhead than the older, pure-python profile module. Together with the excellent
lsprofcalltree script, you can display this data using kcachegrind, which gives you great visualization possibilities for your profile data.
