I tested all of these cables on my home router and measured the boot time for each cable. I changed the direction of the tether halfway through the test to make sure I was averaging the speed and not skewing the results in favor of one direction or the other. The cables aren't labeled with the preferred download direction, so this was the best I could do. I uploaded mostly text data, not videos, so the differences depending on the content might not be that important. However, I found that the red cable has a consistent and worthwhile performance advantage over all cables, but especially the blue. Otherwise they all work well and reliably, and a few colors come in handy, especially in a cluttered closet like mine. My router doesn't document a preferred wire color, but I've found several articles online that mention a similar result.
