So grab the code in 'top' or 'ps' that calculates the process cumulative cpu time and run that twice, one second apart, then do the subtraction and express as a percentage. Depending on your philosophy of MP, divide by the # of CPUs. WTP? > As I couldn't find something that does the calculation on a per second > basis, I started to write something on my own.
