     172== Profiling Deluge daemon with ==

     174The daemon can be profiled using the command line option --profile.  
     175{{{ 
     176deluged --profile 
     177}}} 
     178Deluge 1.3.X uses [http://docs.python.org/2/library/hotshot.html hotshot]. You can convert hotshot profiling data to [http://kcachegrind.sourceforge.net/html/Home.html KCachegrind] calltree format using hotshot2calltree: 
     179{{{ 
     180hotshot2calltree -o deluged_calltree.profile deluged.profile 
     181}}} 
     182git-master uses cProfile so the output can be opened directly by [http://www.vrplumber.com/programming/runsnakerun RunSnakeRun]. To open this in KCachegrind (-k option opens the result in KCachegrind automatically): 
     183{{{ 
     184pyprof2calltree -i deluged.profile -k 
     185}}}
