I was profiling the CPU usage of a sample java app with Netbeans 8.1:
Profile of the cpu time for classes:
I've read the Profiler documentation and I found the difference between CPU and Wall Clock time, and that "Total Time" and "CPU Time" are equal to "wall clock time" and "CPU time". But in the documentation I couldn't find info about the percentage in grey by the side of the usage time in the Total Time and CPU Time columns: Is this the percentage of CPU usage per core?
CPU usage never hits 100%. Does Netbeans profiler measures CPU usage like VisualVM?
