As Daniel told me two days ago, cpuTime shows the absolute CPU time
consumed since boot. To get % CPU time, take two readings 'n' seconds
apart and calculate the delta between them.
I guess so, but what is the precision of the returned cpu time. I
don't think it's 1/HZ as host machine is according to my experiments.
Thanks for your reply.
