I am trying to figure out how to calculate a process' percent cpu usage using the data out of /proc/PID/*

I am assuming it needs to be calculated since I am not seeing a field anywhere in there.

I am already parsing the data, but having trouble figuring out what calculation I need to do. I am looking for the same value top displays as %CPU.

I'm trying to do this purely in perl, without C or running ps in backticks...
