If, IF you have a managed switch, that you can force the Cat5e - Cat6 - Cat6+ port to 100 full duplex. Now the quality of your patch cables, and your infrastructure must be Cat6 or higher. You can not use your own build cables. Not even the ones they sell at Best Buy, or New Egg. HI quality, is the ONLY way you get great through put. I've run an terminated, and tested Cat6, as high as 9db. That's amaizing! Math has nothing to do with a bad connection or patch cable. IDK if you can push the Pi Ethernet to Full Duplex or not? I'm running off a dumb switch. The HP 108 is the smallest managable layer 3 switch, i have one in my backbone. You have to have cables from Anixter, Grainger, professional suppliers.

Twists of each set of pairs are engineered to a specific length. This diminishes/eliminates cross-talk between pairs, based on the sinewave of each signal.
