Anyone have experience using a Netgear R9000 (aka Nighthawk X10 AD7200) as a router? It has a SFP+ port that supports various 10g card types. I am intrigued as both openwrt and dd-wrt support it, and the 10g port can be used as the uplink. Also, just so I am clear, will the Sonic equipment connect to the router via RJ45 or does it support other options (I hear SFP+ 10GbaseT RJ-45 cards modules tend to run hot).
Multi-tcp-stream testing makes the ISP look good, but can mask subtle packet loss and buffer-overrun issues.
The PON upstream MAC can introduce some latencies, opening the potential for bulk packet drop at the (often under-buffered) ONT during sustained upstream transmission.
It would be interesting to see results for single-tcp-stream testing. (Especially for the upstream direction)
I reviewed the SpeedTest-CLI and cannot identify a way to force it to use single-tcp-stream operation. (Wireshark shows it is opening multiple tcp channels in parallel.)
Browser-based SpeedTest.net has a provision to force single-stream operation. But the overhead of dealing with the browser can adversely affect test results. IPERF3 seems to be the only reliable single-tcp-stream test available. And there are no public iperf3 test servers in this country.
Is there an undocumented way to force the speedtest-cli to operate in single-tcp-stream mode?
