We regularly copy a few hundreds of gigabytes of data from a host
running Fedora to a LaCie USB 2 hard drive in order to ship the data to
an overseas company. We've noticed that initiating the copy causes the
load on the machine to creep up and the machine to become very slow in
response. Stopping the copy causes the load to slowly come down again.
Machine is a quad processor (or dual dual-core) AMD Opeteron box running FC3
