Don't do that yourself. There's the performance counters built into GNU
Radio, which allow you to perform the overall consumed work() time, and
if you need to look deeper into your program:
Get the perf tools. Build your project using "cmake
-DCMAKE_BUILD_TYPE=RelWithDebInfo ..", and then
perf top -a python yourflowgraph.py
perf report
Best regards,
