Processes that are waiting for something to happen, e.g. I/O to complete, can't use the cpu even if it's idle. Thus it's perfectly possible to have the cpu doing nothing while the load average is high. It often means you have some long I/O operation on a slow disk system e.g. copying a DVD to an external USB device, or multiple downloads waiting for data to arrive from the net. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
