Thanks to everyone chipping in.
What I am most interested is how the multicore CPU performs. So I am most concerned with understanding the CPU Usage info. which has a number of windows.
E.g. I have a i960, which is supposed to be 6 x CPUs, but the there shows up 8 windows, and during certain intensive tasks, e.g. video conversion, all eight windows have activities. How do I relate that back to a Hex Core CPU with these 8 windows?
Is there any in depth turorial about this?
