Using cProfile results with KCacheGrind

by

With cProfile you can also profile existing programs, without making any separate profiling script. Just run program with profiler

python -m cProfile -o profile_data.pyprof script_to_profile.py

and open profile data in kcachegrind with pyprof2calltree, whose -k switch automatically opens data in kcachegrind

pyprof2calltree -i profile_data.pyprof -k

For example profiling whole paster server and webapp would be done like this

python -m cProfile -o pyprof.out `which paster` serve development.ini

pyprof2calltree can be installed with easy_install.
