We first run our perl program enabling the profiler
perl -d:DProf update_vpp
(we have then renamed the produced tmon.out file to update_vpp.tmon.out to store it with a unique name in our repository)
We generate a graph for the update_vpp.tmon.out profiler data using a threshold of 5% (only subroutines where more than 5% of the time was cumulatively spent are shown).
./dprofpp_grapher \
--format png \
--in update_vpp.tmon.out \
--out update_vpp.tmon.png \
--threshold 5 \
--min-hue 0 \
--max-hue 80 \
