[ 4 / 4 ] Application profile is long enough (23.28 s)

To have good quality measurements, it is advised that the application profiling time is greater than 10 seconds.

[ 2.95 / 3 ] Optimization level option is correctly used

[ 2.95 / 3 ] Most of time spent in analyzed modules comes from functions compiled with -g and -fno-omit-frame-pointer

-g option gives access to debugging informations, such are source locations. -fno-omit-frame-pointer improve the accuracy of callchains found during the application profiling.

[ 2.95 / 3 ] Architecture specific option -x CORE is used

[ 2 / 2 ] Application is correctly profiled ("Others" category represents 0.07 % of the execution time)

To have a representative profiling, it is advised that the category "Others" represents less than 20% of the execution time in order to analyze as much as possible of the user code
