Hi
I am running a userspace tool that reads/writes ISO data from a USB device. ( ISO means periodic data). I am measuring load created by the tool using 'top' tool which shows CPU usage as 0% sometimes and 40% sometimes.
If the data is periodic why the CPU usage vary so much ? Can any one point out what is the missing link ? Does any have a better approach to measure CPU usage.
Thanks in Advance
