I am running VxWorks with kernel version 1.6.0.6 on a single board computer with 8 cores. Now there has been a change of hardware and the new SBC comes with a processor with 12 cores.

I want a way in which I can evaluate the CPU performance in both hardware systems. As in, I want to evaluate the individual CPU core utilization and check the total throughput.  
I came across a command called spy but I could not find more information of how to use it efficiently.  
I would love to hear any other methods I can use in VxWorks that can be used to compare throughput

Thanks!
