(Get the code!)
I seem to have happened upon a "solution".
I added pci=routeirq to the grub boot options and I got my USB and network performance back, and the GUI is actually *usable* while copying files too!!!!
I haven't run extensive tests, but I've been able to copy simultaneously over the network and to two USB devices at the same time with the transfer speed remaining constant, near the speed that I've been expecting (for so long), and I've done that repeatedly. That simply was impossible previously.
Over time I checked for this problem on three computers, and found it on all of them. Coincidentally, the three affected computers are all dual core AMD systems no more than 18 months old running various nVidia chipsets from various manufacturers.
This problem needs to be investigated because I can't be so unlucky as to have seen this bug so often and yet have the bug be one that "only some people get". Many more users out there must be experiencing this on a daily basis and thinking that "Ubuntu can't copy files properly", not realising that there's something wrong, and getting more and more frustrated, as I have been.
