Profile applicability: Level 1 - Master Node
Disable profiling, if not needed.
Profiling allows for the identification of specific performance bottlenecks. It generates
a
significant amount of program data that could potentially be exploited to uncover
system and
program details. If you are not experiencing any bottlenecks and do not need the profiler
for
troubleshooting purposes, it is recommended to turn it off to reduce the potential
attack
surface.

NoteBy default, profiling is enabled.
