nous.pystat =========== An extensible profiler for Python based on Andy Wingo's statprof from http://wingolog.org/archives/2005/10/28/profiling Installing ---------- You need Python 2.5 or newer (but Python 3.x is not supported). Do the usual setuptools/distutils thing, e.g. :: git clone git://github.com/Ignas/nous.pystat.git easy_install nous.pystat easy_install py-itimer Profiling Python code --------------------- This is a statistical profiler, so it should have less overhead than, say, cProfile. It is also not as accurate. Most importantly, it's unsuitable for profiling I/O-bound *or* multithreaded applications. Usage: >>> from nous.pystat.statprof import start, stop, display, reset >>> reset() # optional >>> start() >>> ... do your computation ... >>> stop() >>> display() This use case is unchanged from Andy Wingo's statprof, and more documentation can be found with >>> help('nous.pystat.statprof') There is one new convenience function: >>> from nous.pystat.statprof import run >>> run(function_performing_some_computation, *args, **kw). Profiling ZODB object loads --------------------------- This is a neat hack that monkey-patches ZODBs object load method and collects accurate data on the number of persistent objects loaded during runtime. Usage:: from nous.pystat.zodbprof import zodbprof @zodbprof def my_function(...): ... Every time that function is executed you'll see a summary output on stdout.
