Just installed and activated my new SB6141 so I'm ready for the jump to 100/10. Seeing 8x4 here in 27513, but 20/2 plan still giving just 24/2.5. Bring it.
Ping time is more a function of routing paths and latency. So the distance to the server typically matters (Duke vs Wilson). Bandwidth is a capacity measure. From a latency perspective copper is actually "faster" than fiber as the propagation speed of the signal is higher in copper. Now the bandwidth in fiber is higher but the signal actually travels a bit slower in fiber (speed of light divided by approx 1.5). Free air signal propagation is fastest of all at virtually the speed of light but achievable bandwidths typically far less than fiber.
So don't correlate faster bandwidth with quicker pings. They are different things.
While this is an interesting bit of trivia about copper being faster than fiber, you really need to add more context so that people don't draw the wrong conclusions. Fiber is vastly superior over longer distances due to the greater signal attenuation in copper cables.
Adding a bit more detail, the bandwidth-distance product of fiber cable is roughly ten times greater than copper, which means that the same signal bandwidth can be carried ten times farther with fiber. This property has made fiber the clear choice for network links over 100m for quite some time. Cable and phone companies are trying to squeeze every last bit of signal bandwidth out of the old copper wires running to our homes, but it's a huge uphill battle when compared to fiber.
Regarding end-to-end latency, long-haul fiber connections between cities are the best way to reduce it. You take a whole bunch of individual fiber cables, each transmitting at a lower bandwidth over a greater distance (minimizing signal repeaters), and aggregate them into a high-bandwidth link. Copper can't really beat this approach when it comes to latency reduction.

I too just installed SB6141...and waiting but happily slogging along at 20/2.
My issue is coverage in my house. Extender helps but could be better signal (speed test showing 8-9/2). Maybe 100/10 = better??

i have same modem, how do you see that you're getting 8x4?

My comments were relative to latency. Bandwidth and loss are different issues. That was about all the detail I could stand typing on my phone
Depending on the application, users can be concerned with one aspect more than the others.
Maybe trivial to some, but Financial trading markets can be very focused on minimizing latency as trading profits can be very time sensitive. That can sometimes run counter to the normal network design criteria.
But the point was that, as a general rule, I think many folks (not RDUBiker) often believe that shorter pings and higher bandwidths work hand in hand because we use words like "faster". Indeed, higher bandwidth may drive a faster screen refresh but it doesn't drive faster ping times.
Another trivia point - some of the first optical fiber telecom systems in the US were designed in Raleigh including the first singlemode US system to carry live customer traffic in the US - can you imagine 90Mbps! . A fair amount of early WDM (Wavelength Division Multiplexing) work was also done in Raleigh ... all in the '82-'84 timeframe ... and the first optical self healing "rings" were also designed in this area. ATT/Bell Labs gets lots of deserved credit, but a couple of Triangle companies played a significant role too.
Extreme still running 35/6 up/down here ... pretty consistently.
I remember in probably 1992 I was doing some work at Alcatel when they were off Wake Forest. This was just after they shut down a PCB line there and converted much if the building to office space. I remember seeing a test lab off an engineering office with windows in it. They had the usual racks full of various parts. A big sign over it all said "Fiber to the Home/Curb"
I also know from working on IBMs campus and with some other buildings that they have a pretty extensive private fiber network in the area and have for a good while.
Now, as far as financial markets, I've heard they have started using Microwave links in some places in NY and NJ since no cable can truly be run in a completely straight line, needing to route with streets and around buildings and that costs measurable time off the trip.
Now, back to the topic, should I reboot tomorrow AM or is it Thursday?

This is the only thing that matters right now.
