Some interloper wrote to this thread who was suspended for SPAM, but since they raised an issue claiming the CLI speedtest uses one server, and the portal uses more than one, I can report the following:
My config:
Service is rated at 1000 Mbps (1G) download, 20 Mbps upload.
My Xfinity router (vendor is Technicolor France) tests 1140 Mbps download, 23.5 Mb[s upload
The router is connected via 2.5GE to a NethServer gateway, using a small fanless Intel 4th gen i7, with a RealTek 2.5G Ethernet adapter.
I have a desktop with GE NIC running Windows 11, connected to the NethServer through a couple of GE switches, and one link is an RG6 coax cable with two DOCA connecters. DOCA connectors are rated at 2.5G, but both ends are connected to GE switches, so they run at GE.
I get typical results
- (I don’t know if this test uses Speedtest or something else) from my Xfinity-branded Technicolor (France) router, configured as a router (not a bridge), accessible from the Xfinity Android app, but I got 1140 Mbps down, 23,5 Mbps up
- From NethServer Speedtest-CLI, I got 1040 Mbps down, and 23.5 Mbps up.
- From Windows 11 PC with GE adapter, I get 950 Mbps down, and 23.5 Gbps up.
