Surfing the internet with 1 GBit/s

Adding 30 Cents to my monthly bills bought me Gigabit internet access. I now pay 39.99 EUR per month. Previously I had 100 MBit/s. From user's experience I do not feel any significant difference. Of course, for all my mobile devices, like smartphones, laptop, there is and will be no difference as Wi-Fi does not really offer high transmission rates, unless you are very close to the emitting antennas.

Speed measured by speedtest.unitymedia.de. I get similar results using speedtest.

I assume that the contacted servers itself or the routes to these servers have bandwidth restrictions. Google also provides a speedtest: google.com/search?client=firefox-b-d&q=speedtest. Results are as below:

Previously I used an Odroid as a central IP router. This is no longer a good option as the Odroid with USB-Ethernet interface can get 200 MBit/s at best. So I connect my LAN cable based PCs directly to the cable modem.

The subjective feeling that "the whole internet" is not faster than before, is exemplified by the usual pacman -Syu, i.e., the regular update. So many servers I contact do not provide the speed which I could handle.
