@Sergei_Shablovsky said in Speedtest (Ookla) on device? What’s the latest?:
BTW, does anyone actually get 1 Gb on a 1 Gb connection? Seems to me there should be some overhead accounted for. I also get around 920 with iperf over my LAN.
Please read (or look on YouTube) basic of networking, what is tcp/ip, ICMP, VPNs and other protocols, what is levels, datagrams, what is routers/switches, how ISP works etc. ;)
I guess you haven't noticed me on this forum for years providing advice to others. My comment was to point out that if you have a 1 Gb connection, you will not see 1 Gb because of the various overheads. We're also running into hardware limits that we didn't see before, because the bandwidth we received was less than what our hardware was capable of. In my own example, my account is supposed to be 1.5 Gb, but my firewall, switch and computers are only capable of 1 Gb. I also did a comparison on my network, with Speedtest from my computer to my ISPs server and also from my computer to firewall with iperf3 and got similar results, which showed I was being hardware limited, not Internet limited to the Speedtest server.
BTW, I have long worked in the telecom industry, mostly as a technician, going back to 1972, have worked with computers since 1977, first LAN experience in 1978, Cisco CCNA and more. I also had TCP/IP courses at a local college and IBM. I also spent almost 4 years at IBM Canada, providing software support (mostly 3rd level). So, I do have some idea about what happens with networks & the Internet.
