I'm using profilescope to identify performance issues in my code
(vxWorks 6.2). I'm finding that "(Kernel State)" consuming 25% of my
CPU at the peak usage. I hope somebody can clarify:

1. What really constitutes Kernel State?
2. What are the common reasons for high CPU usage by this "task"?
3. When CPU is running @100%, what could be the acceptable range(cpu
consumption) for this "task"?

Thanks,
