This seems to create weird (as in incorrect) looking results. Here the ones 
from Matthias Fritzsche:

[2018-05-21 18:19:41] <txt-file> ordexm, marec, ecsv_: Now I have one router and the its neighbour with batman_V with tp-meter. https://paste.debian.net/1025691/
[2018-05-21 18:24:28] <txt-file> ah … now "batctl n" shows a tp of 16064.1
[2018-05-21 18:29:07] <ecsv_> uhm, isn't this rather... high
[2018-05-21 18:29:53] <txt-file> ecsv_: I think so. This node has an upload of 4 MBit/s
[2018-05-21 18:30:34] <txt-file> now (6 minutes later) tq=2.2
[2018-05-21 18:30:48] <txt-file> which sounds much more realistic.

The setup is using an gluon based router (TP-Link TL-WDR3600 v1) [1] which 
uses a vpn connection (fastd) to a server 
(descartes.routers.chemnitz.freifunk.net) in the internet. The automatic 
throughput test runs between these two devices.

Kind regards,
	Sven
