Profiling

Build with gperftools, and ensure that it’s built:

$ grep profile Make.inc
GPERFTOOLS_LIBS	= -lprofiler

Run your test using the profiling tools. One signal will start the profiling, another will stop it.

env CPUPROFILE=/tmp/freeradius.prof CPUPROFILESIGNAL=12 freeradius ...
killall -12 freeradius
  ... wait ...
killall -12 freeradius

View the results

pprof --text /path/to/freeradius /tmp/freeradius.prof

or as a graph

pprof --gv /path/to/freeradius /tmp/freeradius.prof

or as cachgrind output

pprof --cachegrind /path/to/freeradius /tmp/freeradius.prof
