Hi Felix,
Currently I also need to profile and optimize my system. Now I just add some some sentences to print the processing time of each block, but this is definitely not a good method. Could you describe your profiling method in more details, perhaps your results can be a reference for me.
Hi Tim,
Have you tried this Kcachegrind on GNU Radio flow graphs? Does it works well? I want to see the profile of each gr module (in python).

Hi all,
I am currently trying to optimize the performance of my DRM transmitter
and for this purpose I want to profile my flow graphs.
After some googling and searching the archives I stumbled upon oprofile
which looks quite nice to me. However, a first try did not really provide
very significant results. But that could also be due to misconfiguration,
I did not read the manual very carefully...
Just wanted to know if there are other/better solutions for profiling you
would recommend. Any comments are appreciated!
Best regards,
Felix
