I have two PCs connected to the net through Belkin wired router and have file sharing between the two (Microsoft Home Networking). When I transfer a large file the CPU usage reaches almost 100% and it's difficult to do anything else. My primary PC is connected via the onboard LAN on Abit NF7-S motherboard and I have tried a PCI NIC with no noticable difference. Is this Normal? Can I do something to reduce the CPU usage? Should I use 3rd party programs to transfer files between my PC and cancell file sharing on Win XP? any suggestion would be grately appreciated. Thnks.
