I'll pitch `perf` here (you're on Ubuntu, so it's in the linux-tools, probably).
Build GNU Radio with the debugging symbols enabled, i.e. call CMake with the build type specified:
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
Then, allow normal users to sniff around processes' calls:
sudo sysctl kernel/perf_event_paranoid=-1
Run GRC to see where time is spent (-a is for "all CPUs")
perf record -a gnuradio-companion
play around in GRC. Close it and interpret the result as shown by
