But why does Fingbox slow down my computer by around half the speed? Both Fingbox and Computer are connected via LAN-cable to the same switch. When I do an "iperf" with Bandwidth Analysis it's only half the speed than "normal"…

Using IPERF is rather situational. Did you use a typical local client-server setup?
Anyway, I did a few tests myself. Allow me to show you the results.
The server for the first two runs is a high-end core i9 11900K w/ 64MB, all SSD, CAT7 cable on a professional CISCO managed switch.
The client for the first two runs is a 7th gen Intel i7 (Surface Pro) on a USB 3.0 ethernet adapter, CAT7 connected to the same managed switch.
First, a typical client-server IPERF run, wired, on a 1 Gbps local network (managed switch) and FING fully functional.
The report shows this:
Next, exactly the same IPERF run, but now with FING disconnected.
The report shows this:
Hardly any difference. A tad slower, even (888Mbps vs. 874Mbps). But neglectable.
However, when I do a REVERSE run of IPERF (switched client and server), the following happened, still WITHOUT an active FING:
See the difference? A whopping 40% drop, compared to the first two runs.
Apparently, the server quality greatly determines the bandwidth.
If you do the same experiment, you may observe similar results.
That's why I always say that speed-tests, no matter how consistent it looks, are always very situational.
But I think the conclusion can be, that FING does not impact the bandwidth of your network.

@Popula , it may not be clear that I used bandwidth-analysis-feature of Fingbox which seems to have an impact on bandwidth of the host that is analysed:
- Without this feature, all iperf3 jobs are great and as expected and stable around/between 300-400 Mbit/s (which is very near the maximum that I'm expecting).
- But as soon as I start to analyse bandwidth with fingbox for one of my hosts involved in iperf3, the performance is more than halving most the time , sometimes it's near the expected maximum.
