We are currently working on expanding the Internet Box Speedtest to 10Gbit/s. This will happen in the next few weeks.
This will also be the only way to test the 10Gbit/s. As long as you have a subscription with the appropriate service speed, of course.
It should also be mentioned that XGS-PON has a relatively large overhead. So you will measure approx. 8.2 / 8.0 GBit/s.
As already explained, you will get a maximum of 2.5Gbit/s from the LAN. But you need the appropriate equipment.
Theoretically, it is already possible to carry out tests across multiple ports using iperf3 or other measurement tools. But this requires a corresponding server in the network.
In the laboratory, of course, we did this with the Internet-Box 3. This is to show that the IB3 can also utilize the speed of the new fiber optic technology aggregated across all ports (LAN and WLAN).
