Thank you John, I just installed the tool you suggested and tried to use it. However I do not see any output. Could you give some more detailes of how the profiling process with the google-profiler should look like? What I do is:
1) bjam variant=profile toolset=gcc cxxflags=-fno-for-scope linkflags=-lprofiler test_ext 2) env CPUPROFILE=/path/to/my/dir/out.prof python ./mypythonscript.py This runs my python script which invokes the extension. However it does not produce any output files (which i expect to be out.prof in my working directory). What should I do in order to see the profiling information? By the way, by this time I've tried other two tools suggested. Here are my feelings: 1) oprofile - looks and works good. it is fast enough and produces much useful information, there is a bunch of options to play with. The only inconvenience is that I need to start and finish it only being a root. This means I either have to switch back and forth oftenly or do all profiling (and development as a root). 2) valgrind - also is pretty convenient tool and produces a lot of information (the raw output loooks quite difficult to understand, but i guess there is a play around options). It gives you many options of profiling. The only bad thing - it is very slow. 3) google-profiling - is kind a promising for my purposes, but by this time i still have not managed how to see the output information.
