Profiling the code of FreeCAD helps find bottlenecks in the algorithms used to create or manipulate objects.

To profile Python code use the standard cProfile module to define start and end points to profile in the code. 

import cProfile
pr = cProfile.Profile()
pr.enable()

# --------------------------------------
# Lines of code that you want to profile
# --------------------------------------

pr.disable()
pr.dump_stats("/tmp/profile.cprof")

Then install and use pyprof2calltree to convert the profile output into cachegrind input. 

pyprof2calltree -i /tmp/profile.cprof -o /tmp/callgrind.out

Then visualize this information with kcachegrind for Linux or qcachegrind for Windows. 

kcachegrind /tmp/callgrind.out
