the mentioned tincd...

We ran other tests on our backbone vms. There we build plain l2tpv3/batv15 on top and we got heavy promising results. 
In short: plain we got there 980mbs, with wireguard some 700 and l2tpV3/batv15 on top 500mbs.

we will report that soon as working alternative to tincd, while tincd only interconnet our backbone. 
the small routers run fastd into the backbone. 
That was Indeed this test about, if this could be an alternative or extension for the small nicely working userspace fastd - and curiosity.

On that mentioned backbone tests we have a huge drop in performance when packets where fragmented, everything goes down to stable 50mbs, and raise to stable 500 if unfragmented. we have to solve this mystery before we will come forward, or if we cannot solve this, we may report as is.
