Welcome to the speedtest service of wilhelm.tel. While its main purpose is to serve our access network customers a platform to validate their available bandwidth we happily like to serve users from all over the world.
We encourage our customers to validate their bandwidth using iPerf3. Speedtest.net and Breitbandmessung.de are somewhat odd. iPerf(1) has been discontinued.
iperf3 -c speedtest.wtnet.de -p 5200 -P 10 -4 (for IPv4)
iperf3 -c speedtest.wtnet.de -p 5209 -P 10 -6 (for IPv6)
-R reverse mode (server sends, client receives)
iperf3 -c speedtest.wtnet.de -p 5200 -P 10 -4 -R (for IPv4)
iperf3 -c speedtest.wtnet.de -p 5209 -P 10 -6 -R (for IPv6)
Ports available for testing are 5200 to 5209
Files are served out of a ramdisk in /files.
