It's done, i m now able to use KCachegrind with ZopeProfiler.

Is someone has try to use ZopeProfiler with KCacheGrind ? I would like to try KCachegrind because i found xdot very slow.

I have started to read the code of ZopeProfiler and i have discovered the world of profiling file format. It seems that ZopeProfiler save it's file in pstats format. So i need to convert those file to calltree format. But all scripts i have tryed has failed:

* pyprof2calltree * lsprofcalltree.py * hotshot2calltree

So am i on the wrong way ? Do i need to fix one of these script ? Are you using on of them ?

You could try "pyprof2calltree" from the Python interpreter in the following way:

from marshal import load from pyprof2calltree import visualize # or convert stats = load(open(name_of_saved_file, 'rb')) visualize(stats)

Not sure whether it will work (it probably will when "pyprof2calltree" does not expect a more modern 'pstats' format).

I have try this one. First issue, it assume you are using a Python2.5 (cProfile is new in Python2.5 but assume the same API) so i have change the import

import profile as cProfile

Now got a new problem when trying visualize:

visualize(stats)
