I too thought this was very generous and thank the OP.. Despite being in
industry for over 25 years, I always enjoy these types of presentations, as
there seems to be something new to learn.

Hello,
I wrote an OOT Python module with multiple inputs and when I run the QA

getting caught somewhere. I get one radio station and hiss on the

Hi,
Thanks for the hint, I didn't know about this method of profiling :). I did

Hi,
I'm on the run, else I'd start a Ubuntu VM myself, but:
sudo apt install linux-tools
sudo sysctl -w kernel.perf_event_paranoid=-1
perf record -ag python3 /path/to/your/flowgraph.py

Hi,
I tested on a different machine of mine (Fedora 32, GNU Radio 3.8.2) and
the problem does not occur there.
This suggests that the problem is somehow specific to this Ubuntu system,
but not to a specific build of GNU Radio (nor Python, it occurs with both
3.8 and 3.9). Since this looks more lik
