> Hi again. On a dual-core system, how do I tell how much of each of the CPU > cores are in use? Is the CPU usage in 'top' for the two CPUs at once? Is top in first line sums all CPUs, while at process line gives usage of single CPU. so for example running one CPU-hungry program you will see near 100% CPU at this process and 50% user at top line+50% idle
