Profiling a long running python program

+++++++++++++++++++++++++++++++++++++++

1. Add the following program into source file and call as decorator

import cProfile

def do_cprofile(func):

def profiled_func(*args, **kwargs):

profile = cProfile.Profile()

try:

profile.enable()

result = func(*args, **kwargs)

profile.disable()

return result

finally:

profile.dump_stats('/tmp/profile_bin.prof')

return profiled_func

2. Convert the profile_bin.prof to human readable file

import pstats

f = open('/tmp/human_readable_profile.prof', 'w')

stats = pstats.Stats('/tmp/profile_bin.prof', stream=f)

stats.sort_stats('cumulative').print_stats()

f.close()
