Lot of information is available in the Python documentation website: http://docs.python.org/library/profile.html . However, here is a small snapshot of how to use it :
Let us say you have a function call test(). First you need to run it:
import cProfile cProfile.run('from your_module import test; test()', 'prof') |
It will save profiling results in ‘prof’, which can then be parsed with pstats module:
import pstats p = pstats.Stats('fooprof') |
You can then introspect the data. For instance the following code sort the results by time and print the 10 largest one.
p.sort_stats('time').print_stats(10) |
