Looks fairly normal to me - I'd expect a lot of waiting for I/O during a big copy because rotating disks are incredibly slow relative to processor performance. The CPU is also generally having to work harder on a 32bit machine with > 1GB of RAM doing MMU management due to the lack of address space.

The scheduler btw is kernel side so doesn't get paged/swapped out.
