I think this can be accounted for the inaccuracy of the time measurement, or the /proc/stat file. 1
The value after the slash is the number of kernel scheduling entities that currently exist on the system. These stats are shown in the 3rd row from the top command. I am using embedded Linux in a small system. Calculate Cpu Usage From /proc/stat Is there a way from code, or by parsing some command's output to get the CPU utilization stats?

Reply Link Mani January 26, 2011, 6:08 pmGreat article.. Is it possible? If I see a load of 1.57 (157%) on a Xeon (quad processor), is that 1.57 out of a possible 4.00, or are all 4 CPUs running flat out and swapping Linux Cpu Usage Per Process The first of these is the number of curâ rently executing kernel scheduling entities (processes, threads); this will be less than or equal to the number of CPUs.
