+#  GOOGLE PERF TOOLS
+#
+#  Repository: https://github.com/gperftools/gperftools#readme
+#  Documentation: https://gperftools.github.io/gperftools/
+#
+# Install (Ubuntu):
+#  sudo apt-get install google-perftools libgoogle-perftools-dev
+# Note: dependencies above are already installed in docker
+#
+# Usage:
+#  1. To enable the gperftools you need to compile with the -DWITH_PERFTOOLS=ON compiler flag. You can use CCUSTOMOPTIONS above to set it for the dashboard compiler
+#  2. Configure the variable below accordingly to your needs
+#  3. run the worldserver with the "./acore.sh run-worldserver"
+#  4. run "killall -12 worldserver"  This command will start the monitoring process. Run "killall -12 worldserver" again to stop the process when you want
+#  5. At this time you will have the .prof file ready in the folder configured below.
+#  Run "google-pprof --callgrind <path/of/worldserver/bin> </path/of/prof/file>" This will generate a callgrind file that can be read with
+#  QCacheGrind, KCacheGrind and any other compatible tools
