I wonder how well PXE boot + NFS shares would fare in comparison? Hasn't a lot of the USB stack been pushed into user space in more recent operating systems?

One thing to keep in mind is that USB 3.0 is a completely different independent controller from 2.0. So, just because USB 2.0 sucks doesn't necessarily mean 3.0 does. It's just unfortunate because you would expect 2.0 to be well optimized by now. I assume the kernel driver must be using the CPU to shovel data from the USB 2.0 controller rather than DMA.
