Performance profiling is stopped by running the profctl utility again, using the -stop option:
% rsh trumpet arun profctl -stop
When performance profiling is stopped, a raw data file is generated for each profiled component within the /tmp directory of the target file system. The name of the file consists of the component name, to which the suffix .prof is added. For example, if only the_actor was profiled, the file $CHORUSUS_ROOT/tmp/the_actor.prof would be created.
