This might be better in fc6, I made some changes related to this
I am running FC6, and I am getting 100% CPU usage when copying from a windows share in the same network segment (didn't test with other configurations). I am running FC6 with kernel 2.6.18-1.2798.fc6-i686 and nautilus-2.16.2-5.fc6. The computer is a Toshiba Tecra M1 laptop.
