SOLVED! Ok, I have concluded my assessment of the performance problems noted above. THE WINDOWS 7 IP STACK IS A PIECE OF SHIT! If you look at my results, you will see a massive performance improvement recently. That's because I have upgraded my PC to Windows 8.1. Nothing has changed except the OS. My performance is on the order of over 10 times faster. My advice for those of you who want to get to faster network performance, use Windows 8 or 10.
