Public iPerf3-Server speedtest.wtnet.de upgrade to 40Gbit

Hey guys,

some of you may know me from LEB as "fLoo". I'm running the public speedtest server "speedtest.wtnet.de". We've successfully upgraded it to 40 Gbit. It is located near Hamburg/Germany. I'd be happy to hear results from you to improve on them.

https://speedtest.wtnet.de

Thanks for your time!

Florian

  • No, I didn't knew that such server or person even existed. Thank you for letting me know. 40 Gbps iperf is better than 0 Gbps.

    I bench YABS 24/7/365 unless it's a leap year.

    Thanks for letting me know. I'm in the process of generating these files now.
    Update: Should be fixed now.

  • Thanks for your public service! There are not enough iperf public servers out there especially ones to test speeds higher than 1Gbps. So thank you!

    Cheap dedis are my drug, and I'm too far gone to turn back.

    yeah i also got an AMS HostHatch it never realy goes above 3Gbps.

    We can help you with a test or monitor point at Tampa, FL.

    Great project after all.

  • I'm currently checking into tunables and routing issues with out backbone. Please give me some time to so i can hopefully fix this. Within Germany I've seen tests up to 19,8 Gbit so far. Yet not close enough to 40G. Sorry. Will update this post once i can update you with hopefully good news on this.

    It's a netcup box . :)

  • Update:

    It looks like everyone is testing against one single Port. Because iPerf3 is single threaded i'd like to ask you to test the throughput the following way:

    iperf3 -c speedtest.wtnet.de -s t1 -p 5301 -P 2 -4 &
    iperf3 -c speedtest.wtnet.de -s t2 -p 5302 -P 2 -4 &
    iperf3 -c speedtest.wtnet.de -s t3 -p 5303 -P 2 -4 &
    iperf3 -c speedtest.wtnet.de -s t4 -p 5304 -P 2 -4 &

    I was able to verify that i was able to achieve 100G locally using 4 ports (25g each using 2 threads).

  • have u tuned the TCP Settings (rmem wmem congestion_control etc..) on the Box ?
    Could help to increase the Speeds

    Yep. According to ESNETs advice for 40/100g interfaces

    From NY seem to only be able to push around 3Gbps tried using the above commands looks like it has a typo in it.

    Running the above with multiples doesn't seem to help our speeds.

    We will have a 40g system online for a bit here if someone wants to test it out have fun.

  • @uniquoo said: I'd be happy to hear results from you to improve on them.

    I've tested from my home connection (Vodafone Cable with 1 Gbit/s down, 50 Mbit/s up) and I get about ~850 Mbit/s down and 50 Mbit/s up while I get close to 1 Gbit/s down with Clouvider's iperf servers in AMS and FRA. But that's likely due to the peering between wilhelm.tel and Vodafone?

    Looks like they're peers so should be good?

    I'm getting around 940/940 Mbps on my home connection at the moment. That's in the Netherlands, but my ISP has IX peering with WTNet too. Best I got from this speedtest server was ~ 16 Gbps on a 40 Gbps connection.

    To be honest with you, i've yet to find the bottleneck which causes the problems described. I've tested locally with multiple streams (using multiple ports and so multiple iPerf3-daemons on multiple cores) and was able to achieve 100 Gbit consistently.

    Right now i'm debugging with our backbone department to rule out anything between the server and our core router and/or between the core and the endcustomer. Not that of an easy task.

    Tested from our speedtest:

    Interesting, yeah it seems odd on the speeds. I know someone else did some tests and got 18Gbps in PHX.
