We have a network with what seems like 100MB equipment everywhere but there are problems with the slow network. I tried to do a simple test to test the speed. From a Win7 computer I mapped a drive on the Win 2003 server with a 100MB switch between them (Trendnet 10/100 8PT w/4pt POE I believe is the exact model). The mapped drive had a 3GB file on it and I copied it to the local drive.
The 'detailed' copy dialog box reported a speed of a fairly consistent 11MB per second. I wouldn't expect the speed to be 100MB but I would think it would be faster than 11. The only other component is the actual Ethernet cable itself isn't it? Could that make a difference? What possible bottlenecks would cause this?
