Thanks for this useful and needed explanations on top activity report!
I'm playing at the moment with iMX27 board and I want to profile the behaviour of the single app running on it. But, even after this article, I still can't figure out why I can have a 1-mn average load of 0 with a CPU% being about 6% (in this snapshot) but can go up to 53% and is most of the time in the STOP state!
if 6 to 53% of instructions executed by the CPU belongs to my app why the CPU seems not to be loaded and why the log still report an activity while the process is in a Stopped state?...
Here is a snapshot of the log activity of the App (matrix computation,for a kalman filter implementation, size might be in the worst case a 20 square matrix)
